Re: [Python-Dev] NotImplemented comparisons

Guido van Rossum schrieb:

NonImplemented isn't treated as special when returned by __cmp__(); __cmp__ is not considered a binary operator like __add__. (__lt__ and friends *do* get treated as such -- but instead of __rlt__ we use __gt__, etc.)

But if it's not treated as special, why doesn't the comparison raise an exception, like when __cmp__ returns "foo", for example? Georg -- Thus spake the Lord: Thou shalt indent with four spaces. No more, no less. Four shall be the number of spaces thou shalt indent, and the number of thy indenting shall be four. Eight shalt thou not indent, nor either indent thou two, excepting that thou then proceed to four. Tabs are right out.
