Good point, but there's actually another problem I forgot to mention. In a &{}, undef is code.

That's not true. Why is your eval always returning 1 unless it dies? With 

sub is_code {
    no warnings qw( void uninitialized );
    return eval { defined &{$_[0]} };
}

things look more reasonable. If undef were code, it'd be a serious bug.

--shmem 

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}
