I'm also +1, I agree with Donald that "|" makes more sense to me than "+" if only for consistency with sets. In mathematics a mapping is a set of pairs (preimage, postimage), and we are taking the union of these sets.
An option might be to allow a union "|" if both the (key, value) pairs that match in each are the same. Other wise, raise an exception. Ron
