    // CompoundString uses available buffer space to directly store characters or pointers, or to pack information such as a
    // substring's start index and length. It is optimized for concatenation. A compound string begins in direct character mode,
    // where it appends characters directly to the buffers. When a somewhat larger string is concatenated, the compound string
    // switches to pointer mode and records the direct character length. From that point onwards, only pointers or packed
    // information is stored in the buffers. Each piece of packed information is stored as a pointer with the lowest bit tagged.
    //
    // A compound string may have several chained Block objects, each with a buffer allocated inline with the block. The
    // compound string references only the last block in the chain (to save space), and each block references its previous block
    // in the chain. As a consequence, during flattening, blocks are iterated backwards and flattening is also done backwards.
    //
    // -------------------------------------------------------------------------------------------------------------------------
    // Using as a character-only string builder
    // -------------------------------------------------------------------------------------------------------------------------
    //
    // Using the AppendChars set of functions requires that the compound string is in direct character mode, and forces it to
    // remain in direct character mode by appending all characters directly to the buffer. Those functions can be used to build
    // a string like a typical character-only string builder. Flattening is much faster when in direct character mode, and the
    // AppendChars set of functions also get to omit the check to see if the compound string is in direct character mode, but it
    // is at the cost of having to append all characters even in the case of appending large strings, instead of just appending
    // a pointer.
    //
    // -------------------------------------------------------------------------------------------------------------------------
    // Appending
    // -------------------------------------------------------------------------------------------------------------------------
    //
    // The compound string and builder have simple Append and AppendChars functions that delegate to a set of AppendGeneric
    // functions that do the actual work. AppendGeneric functions are templatized and their implementation is shared between the
    // compound string and builder.
    //
    // After determining how to append, the AppendGeneric functions call a TryAppendGeneric function that will perform the
    // append if there is enough space in the last block's buffer. If there is no space, the AppendGeneric functions call a
    // AppendSlow function. In a compound string, the AppendSlow function grows the buffer or creates a new chained block, and
    // performs the append. In a builder, the AppendSlow function creates the compound string and delegates to it from that
    // point onwards.
    //
    // -------------------------------------------------------------------------------------------------------------------------
    // Buffer sharing and ownership
    // -------------------------------------------------------------------------------------------------------------------------
    //
    // Multiple compound string objects may reference and use the same buffers. Cloning a compound string creates a new object
    // that references the same buffer. However, only one compound string may own the last block at any given time, since the
    // last block's buffer is mutable through concatenation. Compound string objects that don't own the last block keep track of
    // the character length of the buffer in their last block info (BlockInfo object), since the block's length may be changed
    // by the block's owner.
    //
    // When a concatenation operation is performed on a compound string that does not own the last block, it will first need to
    // take ownership of that block. So, it is necessary to call PrepareForAppend() before the first append operation for a
    // compound string whose buffers may be shared. Taking ownership of a block is done by either resizing the block (and hence
    // copying the buffer up to the point to which it is used), or shallow-cloning the last block and chaining a new block to
    // it. Shallow cloning copies the block's metadata but does not copy the buffer. The character length of the clone is set to
    // the length of the portion of the buffer that is used by the compound string. The cloned block references the original
    // block that owns the buffer, for access to the buffer. Once a new block is chained to it, it then becomes the last block,
    // effectively making the clone immutable by the compound string.
    //
    // -------------------------------------------------------------------------------------------------------------------------
    // Last block info (BlockInfo object)
    // -------------------------------------------------------------------------------------------------------------------------
    //
    // Blocks are only created once chaining begins. Until then, the buffer is allocated directly and stored in the last block
    // info. The buffer is resized until it reaches a threshold, and upon the final resize before chaining begins, a block is
    // created. From that point onwards, blocks are no longer resized and only chained, although a new chained block may be
    // larger than the previous block.
    //
    // The last block info is also used to serve as a cache for information in the last block. Since the last block is where
    // concatenation occurs, it is significantly beneficial to prevent having to dereference the last block to get to its
    // information. So, the BlockInfo object representing the last block info caches the last block's information and only it is
    // used during append operations. Only when space runs out, is the actual last block updated with information from the last
    // block info. As a consequence of this and the fact that multiple compound strings may share blocks, the last block's
    // character length may not be up-to-date, or may not be relevant to the compound string querying it, so it should never be
    // queried except in specific cases where it is guaranteed to be correct.
    //
    // -------------------------------------------------------------------------------------------------------------------------
    // Builder
    // -------------------------------------------------------------------------------------------------------------------------
    //
    // The builder uses stack-allocated space for the initial buffer. It may perform better in some scenarios, but the tradeoff
    // is that it is at the cost of an additional check per append.
    //
    // It typically performs better in cases where the number of concatenations is highly unpredictable and may range from just
    // a few to a large number:
    //     - For few concatenations, the final compound string's buffer will be the minimum size necessary, so it helps by
    //       saving space, and as a result, performing a faster allocation
    //     - For many concatenations, the use of stack space reduces the number of allocations that would otherwise be necessary
    //       to grow the buffer
