Wrapping tools will always have to be aware of both sides of the wrapper, and deal with differences and ambiguities in one way or another. The simple feature that "with" could then be used unmangled in Python code does not even touch the surface of this.

They would be helped because the other language might have method/function/class names that are reserved works in Python, an example of this is the 'class' method of NSObject in Objective-C.

PyObjC using the convention of adding a double underscore to the end of method names to make them valid Python identifiers ( anObject.class__()).

I'm -1 on the proposal though, the readability cost is too high for the very small benifit of using keywords as attribute names.
