Side point: Wouldn't it be quite logical to support dict addition?
>>> {"a":1}+{"b":2}
Traceback (most recent call last):
File "<pyshell#59>", line 1, in <module>
{"a":1}+{"b":2}
TypeError: unsupported operand type(s) for +: 'dict' and 'dict'
It would make sense for this to result in {"a":1,"b":2}.
