I think that is too verbose and visually baffling. I'd rather see something less general and (in my opinion) more useful:
a, b, c = **mapping
being equivalent to:
a = mapping['a'] b = mapping['b'] c = mapping['c']

Simplest, easiest to grok, probably solves 95+% of the use-cases.
OTOH, you could also do x = SimpleNamespace(**mapping) and use x.a, x.b, x.c. Paul
