I suppose with true signatures you mean something like test($x, $y , @opt).
This can only be added by modifying the parser, something far beyond syntactic sugar.
I heard that p5p recently discussed it but with no real outcome (plz prove me wrong).
The essential problem with defining signatures is that the variables (normally) need to be lexicals.

But that's the point. I recently gave a longer workshop for my client about how to do parameter check in Perl. This really results in much code... and many people where either frustrated or bored.
Many extra features within an easy syntax do motivate people! And maybe one day these extra features could be reused by a "true" implementation of signatures.
