in thread Union of hashes

They are guaranteed to be in the same order. Note though that in both your solution and Biker's solution this is a union of keys. Entries in %b will overwrite entries in %a with their values when they share the same key. There's really no way around this, and it's probably what IvorW wants, but I thought I'd mention it for safety's sake.

    I should point out that while it's simple to redefine the behavior to have values of %a overwrite %b, or vice verse, you can get more customizable behavior using *cough*my module*cough* Hash::Merge. One included way with this module would have values of equivalent keys to be placed in an anon array, but the module allows for specific settings.
