No.  Even if func_ptr had a default expression for
its "param" it would still be unambiguous, because
you need an explicit ".all" to call through a function
pointer when there are no explicit parameters passed.
An implicit ".all" is provided prior to "(" and ".<component>"
but not in other places.

This calls the "P" that takes a func_ptr.
