Re^4: To each() their own

yes I agree that that was a bit vague. What I actually wanted to state was that assuming Perl is not broken for some other reason that the behavior of each() whatever it may be for a given circumstance under the condition of being called after an insert into the has is okay by me, I.E. I can live the possibly random pair of key/value returned.
