Manifold can add methods to classes and interfaces. But it can’t make a class implement an arbitrary interface e.g. I can’t makeArrayListimplementRunnable. However, we can do something else. The main limitation is due to the way Manifold works. Since Manifold changes the call at compile ...
The way we created our iterators, we can also create our infinite iterators. Let us make an infinite iterator that will return a list of all even numbers. classEven:def__iter__(self):self.x=0returnselfdef__next__(self):x=self.x self.x+=2returnx ...
