I think the point Mr. Eppstein was making is that
"for i in seq" can be read as "for all values of i
such that i in seq is true". PEP 276 would break
that, because "for i in 5" couldn't sensibly be
read as "for all values of i such that i in 5
is true", unless "i in 5" on its own were valid and
had a rather unintuitive meaning.
