[Python-Dev] accumulator display syntax

[Guido van Rossum]

I'd just like to pipe into this discussion saying that while Peter
Norvig's pre-PEP is neat, I'd reject it if it were a PEP; the main
reason that the proposed notation doesn't return a list.  I agree that
having generator comprehensions would be a more general solution.  I
don't have a proposal for generator comprehension syntax though, and
[yield ...] has the same problem.
