BTW, many optimizing Schemes define a weaker form of continuation too (call/ec, for "escaping continuation"). Skipping the mumbo jumbo definition <0.9 wink>, you can only invoke one of those if its target is on the path back from the invoker to the root of the call tree (climb up tree like Cheetah, not leap across branches like Tarzan). This amounts to a setjmp/longjmp in C -- and may be implemented that way!
