Tail call out of a block would be harder because the caller's receiver
(the block) (which we are replacing) holds the return context and
callee's (#bar) localReturns would have to be changed to a remoteReturns.
So a new method would have to be made on the fly and the receiver
would have to be wrapped in a new block closure with the return context.
Is tail recursion required for continuations? I really don't understand
continuations, can you give me some pointers?
Cheers,
Anthony
