A fine answer, functionally, but what's with this shift, shift action? It would be more concise, I think, to simply express it as this: 
sub process
{
    my ($type3, $type4) = @_;
    print "Processing type 3 total of $type3 and a type 4 total of $ty
+pe4\n";
    return;
}

Maybe I'm just overly sensitive about shift. Still, with Perl 6 moving towards a full argument declaration, it will be a lot easier to migrate than shift-riddled code.
