In the above case, one less character.

  my ($foo, $bar, $baz) = @_;
  my ($foo, $bar, $baz) = (shift, shift, shift);

Much shorter.  You can also have:

  my ($foo, $bar, @moo) = @_;

But note that:

  my (@foo, $zoo, $bat) = @_;

Is probably not what you want because @foo will suck up everything,
leaving $zoo and $bat undef.
