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.
