Comment #9 on issue 1887 by [email protected]: Separate boolean and
symbolic relationals
http://code.google.com/p/sympy/issues/detail?id=1887
"I think >, <, >=, and <= should default to the symbolic version, but
perhaps they could be automatically converted to the boolean version when
necessary."
Well, I don't think they should default to the symbolic version, I think
I'd rather expect those to be booleans instead.
Anyway, we have to be sure that things like the following work:
if S(2) < S(3):
print('2 is smaller !')
So, if you choose to keep those for the symbolic version, there should
indeed be a .__bool__() method attached, to avoid more common misuses
(though testing inequalities in such a way might be a bit slow).
If not, it would be *really* confusing.
