If the specified `allowed` tag is `bsl::true_type` assign the allocator object at the specified `lhs` address the value of the specified `rhs`; otherwise, do nothing, and, in both cases, return a modifiable reference to `*lhs`. The `t_TYPE` template parameter is typically an allocator type and the `allowed` flag is typically a propagation trait dependant on the calling context, such as `propagate_on_container_copy_assignment` or `propagate_on_container_move_assignment`. Instantiation will fail if `allowed` is `true_type` and `t_TYPE` lacks a publically accessible copy assignment operator. The behavior is undefined unless `allowed` is `true_type` or `*lhs == rhs` before the call.
