Ok, I'm not going to say you're wrong (I most likely am), but I would
like to try to understand why this would be true.
The tokenizer is going to hand back what? 'bareword:foo', '*', 'type:@',
'identifier:ary'?
In which case, it seems to me that you would be right, but there's a big
trap.... Does that mean that if foo has the following:
sub foo();
sub foo($x,$y);
Then you always get multiply, or you always get argument expansion? Is
that going to be counter-intuitive for the programmer who uses a library
that provides such a definition?
