Re^2: setting a scalar = to a hash?

It's a completely useless value

Not completely useless :-) It can be used in a boolean context to determine whether the hash is empty.

That's because hashes will return 0 if they're empty. It's special-cased. :-) Being right, does not endow the right to be rude; politeness costs nothing. Being unknowing, is not the same as being stupid. Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence. Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.	[reply]
