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.
