Comment:
I'm puzzled about this ticket. Why doesn't the {{{is_zero}}} method
suffice? As said by Karl-Dieter,
for general expressions the problem is undecidable, thus if you want to
check expressions that
*reduce* to zero, the name of the method should reflect the fact that
there could be false
negatives.
