It's both ungrammatical, and, in my opinion, ambiguous. For example,
you can't call things with a default argument. It's possible I don't
exactly understand what you're trying to get at with the message.
What's parmnum? The parameter of the function being declared right now?
Or the parameter in the callee that has a default value that has not
yet been processed?
