For review: PEP 308 - If-then-else expression

[Sean Ross]

In this particular case, I'd say it's significantly better...

> if x when C else y:
>     pass

>
> if x if C else y:
>     pass

If this is to be in the language, wouldn't you rather avoid the latter case
above?
If the language adds this construct,  I would argue that since python
already has
a use for if, I think it would be less confusing to have a new word for this
new syntax.

On a different front:

if C?x:y:
    pass

is just nasty...

And, now that I've thought on it some more, I don't care for my other
suggestion much either:

    when C, x else y

but, I'm just tossing things out there...

In fact, most of the time it makes it a non-starter. FWIW, I don't think
it is significantly better than if either (sorry).
