How is that not an assertion, anymore than

	[exists] x [~ (x = y)]

or

	s = (1/2) a t^2

?

I don't mean this as an insult, but it seems to me that much of your
comments on Python in these threads come down to, "The way this works is
not something I would have given this name to."  While that's completely
legitimate, it's hard to see it as very compelling, since your
distinctions seem to me to be fairly arbitrary (x = y is assertion but
ALL x [f(x) = y] isn't?).
