Sorry, I'm not following . . . the default parameter in my example is on the
function "func", not on the function *pointer*.  In the call
    P (func (5));
since an implicit .all is provided prior to "(", why couldn't this be
interpreted as
    P (func.all (5));
[here it's clear that the default parameter is passed to "func"]?
