in reply to key-values swapped

You could do

%test = reverse @hash;

but you would have to look out for collisions with the keys, which could cause you to lose values

    Talking about hurting one's head ...

    Reversing a hash, you have to watch out for value collisions which could cause you to lose keys. At least, from the perspective of the original hash. Just trying to think about both hashes at the same time in the context of keys and values is giving me a headache. Where is my caffeine?

    Update for the humour-impaired: This is a joke. Relax. ;-)
