This would be a terrible violation of functional encapsulation. How do you know that the (e.g.) forOf function isn’t internally using a encapsulated helper function that is making the actual call to the call back. You simply have no way to predict where returning from the current context “up one” means. > > A current method of doing this is by using try / catch but it is not ideal. > Using the above method I believe that it would be able to be better optimized. This technique provides a meaningful semantics because it allows the controlling outer function to define what early return means.
