    Actually, the use of $elem in the map won't work, as the OP used $elem as the "alias" variable in the foreach loop. There is no alias in this map.
    $> perl -e '@array=({mykey=>foo}, {mykey=>bar}), @out = map{ $$elem{my +key} } @array; print @out;' $>
    Use $_ instead, as Joost or Abigail suggested.
