I think it would be convenient and pythonic if dict objects implemented the PySequenceConcat method.

IMO, the chainmap() recipe on ASPN is a much better solution since it doesn't create a third dictionary with the all the attendant allocation and copying effort. It isn't a common use case to need to sum two dictionaries while keeping both of the inputs unaltered.
