Even with mandatory arguments or optional arguments with default values.

Not really.

Perl6 allows much more, like named variables, types and constraints

I wrote a simplicistic source filter to bring the subroutine signatures to almost all versions of Perl. The module is Filter::signatures.	[reply]
