Comment (by vdelecroix):
The two examples in [comment:3 comment:3] and [comment:4 comment:4] are
not exactly wrong in the same way. In algebraic geometry, a scheme is not
a set. And indeed
{{{
sage: P = ProjectiveSapce(2,GF(2))
sage: P in Sets()
False
sage: P.point_set() in Sets()
True
}}}
I do not understand why there is a `__len__` implemented there! It is
inherited from `Parent` as
{{{
def __len__(self):
return len(self.list())
}}}
Haaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
