Or perhaps even a classmethod:
dict.merged(a, b, c) A dict factory classmethod like this is the best proposal I've seen thus far. * It would be nice if the spelling were more succinct (that's where syntax is helpful). Imagine: somefunc(**dict.merged(a, b, c)) That looks an awful lot like somefunc(**chainmap(a, b, c)) How about making d1 | d2 return an iterator?
You could then merge dicts with no intermediate dict:
merged = dict(a | b | c)
some_func(**a | b | c)- Previous message: [Python-ideas] Adding "+" and "+=" operators to dict
