function defaults

[Joerg Arndt <arndt@jjj.de>]

The feature of all args having default 0 is
one of the few things in GP that I dislike.
I guess it is there to stay for backward compatibility.

Hence I dare to ask whether some mechanism would
be possible to disable defaults (unless given),
for individual functions.

Made up syntax:

foo(a, b)=
{
   nodefaults();
   \\ code...
}

then calling foo without both args given
should trigger an error.

(There are certainly other ways, less fugly,
to do this syntactically).

Best,   jj
