in thread sub functions, and strings

Perl doesn't exactly pass by value -- you can modify the calling arguments by monkeying with the values of @_.

All that seems needed here is :
sub concat { join '', @_ }

my $joined = concat( $first_part, $second_part );

    Why the symbolic reference?
    Huh? He didn't say anything about symbolic references. He said "references", and his illustration was as valid for hard references as symbolic ones.

      You're right - it was just such a weird way to modify an argument that it threw me for a loop. It still risks weird symbolic reference behavior if you accidentally assign a scalar instead of a scalar ref to that variable, so I'll stick to my guns( albeit with less tenacity ).
