Type-erased and polymorphic allocators

Defined in header <experimental/utility>
struct erased_type { };		(library fundamentals TS) (removed in library fundamentals TS v3)

The class erased_type is an empty struct that serves as a placeholder for a type in situations where the actual type is determined at runtime. For example, in classes that use type-erased allocators, the nested typedef allocator_type is an alias for erased_type.

Notes

erased_type is removed in LFTS v3 because std::pmr::polymorphic_allocator<> is preferable for type erasure.
