If there was an atomic test for 'is-a-key' (is there?) >if someKey is among the lines of the keys of myArray Actually it would probably be a lot faster to force every key to have a dummy value. This is because if you have 10,000,000 keys and do a lookup, lookup time should be extremely fast and constant on any key(0 milliseconds) because it's using a hash(ie. associative array) and MC can either find it or it can't. On the other hand 'is among' would force MC to try to match each and every line of the keys..until it finds it, and if there are 10,000,000 keys it could take a while.
I agree though that it would be useful for MetaCard to return something other than empty..if a key can't be found..to differentiate between the empty and non existing case.
