Well... this is a trivial expansion of the keyword argument short form proposal
you were very strongly opposed ^_-
So, I suggested `foo(=a)` as short form for `foo(a=a)`, but if we interpret it
instead as `foo(=a)` -> `foo(**{'a': a}`, which is really the same thing for
most purposes, then we could trivially get `foo(=1+3*bar)` ->
'foo(**{'1+3*bar': 1+3*bar})'
I'm fine with this proposal. And thanks Chris for the idea!
