You might remember that map, sort and grep can be chained and they always accept and return lists...
Hm. Passing a listified hash (mixed keys and values in random order) to any of those constructs is a completely pointless exercise.
That is after all, why you are having to define an hgrep yourself.
Better methinks to pass hgrep and hmap a reference to the hash, call the callback with pairs, and have them return a list.
At least then they serve a purpose:
hsort is left as an exercise.
