I doubt that would be considered Pythonic by many people. Chained
comparisons are Pythonic, but not legal but weird combinations like
`a == b < c is not d >= e <= f`.

That's more like it. Unfortunately it doesn't mean the same as Mark's
version:
b >= a <= c means b >= a and a <= c
which is True for a = 1, b = 3 and c = 2;
a <= b <= c means a <= b and b <= c
which is False for a = 1, b = 3 and c = 2.

Indeed.

enough, things got worse.
