Hello fellow Perlites, I've just been involved with making a PAC (point-n-click) person happy with and 'older' version which had the peculiar- ity of the non-comma (newer) and the comma needed when dealing with an anything, but mostly for readdir ala: 
    my @good = grep(s/../../, readdir(DIR));
or
    my @better = grep({-f "./$_", readdir(DIR));

Newer Perls since 5.6.x don't need, nor do they tolerate the comma after the block I can say that I've seen folks try to use 'grep' as it might be in an Unix environ. Not so. And since I didn't use map so much for these maybe that's a way around. Nonetheless, I'll offer something soon if need be. This also goes to the wantarray construct and the man pages for same. I've already written and commented on this but for clarity -- stop moving the data around! 
    my $ar = \@somearray;
    my @array = @somearray;
    # from a function
    my $ar = &fsome();
    my @array = &fsome();
    sub fsome {
        my @interesting - qw(
            one two buckle my shoe
        );
        wantarray? @interesting: \@interesting;
    }

Okay, let me know and thanks. morourke@theworld.com
