I don't know where to find docs for dumb_ptr, but for ref

reference_wrapper(T&);

The constructor isn't explicit so you can have implicit type conversions at
the point of invocation, so there's not necessarily any information given at
the point of invocation.  Plus there is a cast operator, which, like I said,
I removed from c_out and c_in_out to prevent it from being implicitly cast
into a function call that doesn't take a c_out or c_in_out as a param to
prevent confusion.

Keep in mind, the point of this is to have the compiler enforce decorating
the params to functions.
