Lambdas can't turn statements into expressions. (Mind you, I'm not sure
I'm all that thrilled with my suggestion either, I was merely putting it
out for public consumption.)
I have no problem steering the direction, as some others have suggested,
into a more general construct for multiway or lazy evaluation, with the
conditional operator as a degenerate case.

So what did you think of the introduction of list comprehensions? How
about generators? Same "blurring" going on there.
