TBD: improve comment This is an empty class specialization of `allocator_traits` for pointer types that (intentionally) does not define any of the traits typedefs. It's needed in order make unambiguous function overloads that take both a standard allocator by value and a `bslma::Allocator *`. By using the typedefs defined in `allocator_traits` in the signature of functions taking standard allocators, we can ensure that those overloads are not considered when using `bslma`‐style allocators.
