The reason you're using symbolic references is because you're passing a string in. If you pass in a reference to a hash (aka, hashref), then you stop using a symbolic reference and you start using a hash reference.

As for speed, you're completely and utterly wrong. Symbolic references ARE hashes. The hash being used is the symbol table. It actually uses MORE memory because of how the symbol table is implemented.

Did you actually try my suggestions? Or, did you just read them and go "I don't get it."?

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
