What exactly would be the point of such a subroutine? That's pretty wacky stuff, you have to admit.

It would be sensible to define any function like this: 
sub a
{
     print $_,$/;
}

my @x = qw[ 1 2 3 ];
a(scalar(@x));

Which is similar. I can't think of many examples of where a function would only care about how many elements, and not what they are.

But anyway, as I said, it is a rudimentary script. YMMV. I found it handy at cleaning house on a whole whack of redundant prototypes in long scripts.
