in reply to Adding 2 + 2

$result = 2 + 2; print "the answer is $result\n";

Er.. really? global $result? You don't need that variable:

print "the answer is @{[2+2]}\n";

Works under strict and warnings.

--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}

    It often strikes me as a little strange (or unfortunate) to use array ref/deref for this. The scalar version is only one character longer:

    print "the answer is ${\(2+2)}\n";
    A word spoken in Mind will reach its own level, in the objective world, by its own weight
      The scalar version is only one character longer
      golfer habits...

      --shmem
      But I might be parling heck.

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