If I understand correctly, by "escaping continuations" you mean that
you can easily transfer control between the point where the exception
is raised and the exception handler.
If this is what you mean, you can achieve the same effect with monadic
code by chaining monads together
Yes.
José, this is mainly the question of efficiency. You don't need to
establish contact between the distant stack frames, and you may
propagate failures if this happens seldom. But if the escaping
continuation is a frequent case, it might be more economic to "jump".
This is as simple as that.
