$r->print and references: Was RE: Slightly OT - Content-length

Why is that "convenient":

Fast:
        my $x = "fred" x 10000;
        $r->print $x;

More obscure and microscopicaly slower:
        my $x = "fred" x 10000;
        $r->print \$x;

(Hint - Perl passes all values by reference.  The point $r->print doing
an auto-dereference is supposed to be to let you pass a reference around
in *your* code.  Personaly I don't think this was a good idea.  If that's
what the user wanted he could have done it himself).
