well, think about it first. what would happen if a hash allowed
duplicate keys? how would you know which associated value was attached
to the duplicate key? the whole point of hashes is to index by a
string. requiring unique keys is what makes it a hash. in a similar vein
what would happen if you could index an array multiple times with the
same integer? it makes no sense. same for hashes.
