about formal sub routine declartions

[drieux]

I just found this in the perldoc

" Currently Perl subroutines have fairly limited
        support for formal parameter lists. You can specify the
        number of parameters and their type, but you still have to
        manually take them out of the `@_' array yourself. Write a
        source filter that allows you to have a named parameter
        list. Such a filter would turn this:

            sub MySub ($first, $second, @rest) { ... }

        into this:

            sub MySub($$@) {
               my ($first) = shift ;
               my ($second) = shift ;
               my (@rest) = @_ ;
               ...
            }
"

does this still make sense?

does it improve the compiled object any?

and why not

        sub MySub($$@) {
                my( $first, $second, @rest ) = @_;
                ...
        }

????
