Varray & Darray

varray, darray, and varray_or_darray are legacy types that are usually equivalent to vec, dict, and vec_or_dict respectively. They should never be used in new code.

In positions where a type may be observable as a TypeStructure, these types will result in different TypeStructureKind values. This is the only direct effect, but user-defined uses of TypeStructure values may interpret these kinds differently from their vec/dict/vec_or_dict counterparts (this is not recommended).

In all other positions, it is equivalent and recommended to use their vec/dict/vec_or_dict counterparts instead.
