 `TOY_LITERAL_DICTIONARY_INTERMEDIATE` specifies that the literal to be read is a flattened `LiteralDictionary`. A "flattened" compound literal does not actually store it's contents, only references to it's contents' positions within the literal cache.
 
-To read this dictionary, you must first read an `unsigned short` which specifies the size (both keys and values), then read that many additional `unsigned shorts`, which are indices of keys and values. Finally, the original `LiteralDictionary` can be reconstructed using those keys and value indices.
