Yes, that seems like a no-brainer. You'll quickly see if "self" always has a parent that has a "one" ... > Also, why isn't there an _invert_ method just like _add_ and friends? > There's no coercion involved with that one. I think the only reason to have _add_ is to ensure that __add__ is available to do generic coercion work (possibly even promoting up both arguments so that the _add_ called is on neither of the original arguments. For computing an inverse, there is never such work. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
