subroutine signatures aliases feature

Subroutine signatures is an excellent feature, but possibility to make
aliases is very needed.

For example:

sub ( $a, \$b, \@c ), where:

$a – will be a copy of $_[0];
$b – will be a alias for $_[1];
@c – array or aliases ($_[2] .. $#_ )

This will allow to make code much more clear and readable.
