You are correct - a foreach loop builds a temporary list, and iterates over that. That means that when you loop over the keys of a hash using foreach, entries added inside the loop are not iterated over.

For 'one by one' iteration over a hash, have a look at each, but you cannot use that to add elements to the hash on the fly while iterating over it either (well, you can, but it's your foot :) ).

You'll have to iterate over the hash keys again if you want to get at the new values, I think.
