Almost all of your proposal looks reasonable, but I personally find
this quite hard to read; it should be written along the lines of (I'm
not proposing this):

    x for x in iterable; break if x is None

if one is to continue having syntax that is pseudo-correct English - a
trait I am eager to to keep.

In summary, this is hard for me to read because there is no separation
of the statements.


Because I have not other substantial objections, I'm -0 on this. If
you can find a way to "fix" that, I'll be, for all intents and
purposes, neutral.
