...each is meant for looping through the entire hash... - you're dead right - the hash is meant to be invariant over each - from each '...If you add or delete elements of a hash while you're iterating over it, you may get entries skipped or duplicated, so don't...'.

In answer to your question, again from each - '..it can be reset by reading all the elements from the hash, or by evaluating keys HASH or values HASH...'.

The moral of the story/posting is ... please RTFM before you post.

A user level that continues to overstate my experience :-))
