We can direct people towards catch and throw if they want something
like call/ec.  I really want to first get a better idea about the
larger issues sourounding continuations, stack unwinding, etc.

Yes, but I would like it better if we introduced call/ec when we are
pretty certain about it.  It is not difficult to use catch and throw
instead for the time being.

I hope to write something up in the next days.
