Yep.  There's no problem there.  Really.  We're talking about
diagnostic code here.  Performance isn't an issue.

Besides, that same interface permits other uses like others have
posted already:

   std::cout << demangle(mangled_function_name) << std::endl;

Your approach requires the creation of a named temporary and an
awkward calling sequence.  (Yes, I recall that you discussed a
wrapper that provides that interface, but there's no need for the
wrapper as demangle() doesn't need to be performance conscious.)
