I don't get it. What issue is raised by return-to-label that isn't already raised by exceptions? They're practically the same thing, only return-to-label is *easier* to analyze statically, because 'return' can only jump to a label that is lexically (not just dynamically) in scope.
If you want to call a function and make sure control flow does not escape, then in the face of exceptions alone you can wrap it in try/ catch. However, with multi-level returning lambdas, if you are passed a function then you have no way to prevent it from returning early, since it could be a lambda in the lexical scope of your caller.
