Seeing the names isn't too bad; it's just an inspection of the pad.
Don't forget though that defaults come from expressions, not mere
values.
sub f($x, $y = lc($x), $z = substr($y, 0, 5)) { ... }
Here, it would be easy to say that:
* min arity is 1
* max arity is 3
* parameter names are qw( $x $y $z )
but there isn't a simple representation for the defaults.

I'm not quite sure I follow this part of the request. Maybe an example?
Show a small program and what output you'd like to see.
