But they won't return *true* unless they're the same or similar types. > And with operator overloading, < <= > and => could have any meaning you > like: > > graph = a => b => c <= d <= e Are you suggesting that all objects concerned are a magical "graph node object", the <= and [sic] => operators of which return "edge objects", the and operator of which constructs a graph object containing all such edges? That's *horrifying*. And won't actually work. We haven't actually got an => operator, thankfully, and you can't overload 'and'. I bet you could do it in C++ though. -- https://mail.python.org/mailman/listinfo/python-list
