No, because it's still nondeterministic in behaviour. (It's
something of an implied "goto".) If the behaviour is really needed,
better to use callcc to explicitly handle it; IMO, it's probably not
really needed and the perceived need can be eliminated by a little
judicious restructuring of the design and code.
