Hmmm... another idea: If break and continue return keep exactly the current
semantics (break or continue the innermost for/while-loop), do we need
different exceptions at all? AFAICS AbortIteration (+1 on the name) would be
sufficient for all three interrupting statements, and this would prevent
misuse too, I think.
