[issue6410] Dictionaries should support __add__

[Alexandre Vassalotti]

Alexandre Vassalotti <alexandre at peadrop.com> added the comment:

I am against adding __add__ to dict, since merging dictionaries is not a
commutative operation.

If a short syntax is desired for merging dictionaries, the just define a
function. For example: 

def merge_dicts(*args):
  result = {}
  for x in args:
    result.update(x)
  return result
