And foreach over (@array) doesn't build a new array, and foreach over (<FILEHANDLE>) doesn't slurp the whole file either. Not really a hack there. That is what foreach is for. Building a quick list to foreach over is cool, but throwing a huge list together in a hurry is hard, and worse, eats scads of memory.

The while loop is much better for large hashes like this case.
