I agree with Greg.

There are various possible behaviors that might make sense, but having `d.values() != d.values()` is about the only one I can see no sense in. +1

This really feels like a good cade for reading a descriptive exception. If someone wants too compare `set(d.values())` that's great. If they want `list(d.values())`, also a sensible question. But the programmer should spell it explicitly.

So, a helpful error message including something like "Cannot compare dict.values directly, consider converting to sets / lists / sorted lists before comparing" ?
