What's this?

merge!(hash, key, value) private

Adds a new key/value pair to an existing Hash. If the key to be added already exists and the existing value associated with key is not an Array, it will be wrapped in an Array. Then the new value is appended to that Array.

hash	Hash to add key/value pair to.
key	Key to be added.
value	Value to be associated with key.
