I'm not sure if this is doable from the compiler perspective, but what about allowing tuples after `**` unpacking:

+1. I can see the practical utility of the feature, but was strongly against the other syntax proposals so far. IMO, the above alternative does a great job of using an existing feature, and I think it would be rather easy to explain how it works.
If we go in that direction, I'd prefer curly braces instead so that it's more reminiscient of a dict instead of a tuple, although technically it will look like a set literal. Some other possible syntaxes for a dict (which would have to be unpacked in a function call) with string keys equal to the variable name, i.e. {"foo": foo, "bar": bar}: {*, foo, bar} {**, foo, bar} {:, foo, bar} {{ foo, bar }} {* foo, bar *} {: foo, bar :} {: foo, bar} Personally in these cases I usually write dict(foo=foo, bar=bar) instead of a dict literal because I don't like the quotes, but even then I'm sad that I have to write the word 'dict'. So I would prefer that we covered raw dicts rather than function calls, or both.
