Yes, each does not create a list. On the other hand, it does copy the value (and create a new scalar for the key, because the keys in hashes are not full blown scalars).

Which one to use depends, though - if you're dealing with a DBM tied hash, you'd probably not want to use values.. or for some of the half-million-key monsters I'm dealing with at the moment.

Also, I tend to prefer each when I'm dealing with every pair stored in hash but in no particular order, because it reduces redundancy. I don't need to name the hash in question more than a single time.

Makeshifts last the longest.
