Then why even bother with map to begin with? And no, that isn't as clear. Go back and look at Brian's example. All map blocks need to be evaluated for each element in the list, so when you have a multi-statement block, you end up putting the result at the end, all by itself:

  map {
     ...

     $hash;
  } ...;

to make sure the block is evaluated properly. This is a side-effect, and it isn't as clear or as readable as an explicit push would be.
