Comment(by vbraun):
Actually, your last example `M(1,0,0) in octant.rays()` is precisely where
I would like some feedback to the user that he is probably doing something
wrong. Confusing the polytope with its dual is precisely what a beginner
in toric geometry might do, and I think it would be very helpful if there
were more feedback than a successful completion of the command.
How about we don't raise exceptions and keep your "mathematical" sense of
membership but use the python `warnings` module to print a warning. By
default the warning would only occur the first time when the user aims for
his foot...
