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:

  some_func(**dict.merged(a, b, c))

-eric

* I'd go for the PEP 448 multiple kwargs-unpacking clauses, but as
already noted, the keys are limited to valid identifiers. Hmm, perhaps
that could be changed just for dict()...
