Well, that's exactly what it is intended to do and what I would expect it to do ! break/continue affect only the inner-most loop. > > Am I understanding this right, or am I misunderstanding this? > > If I am understanding this right, I would suggest allowing some way of > having the iterator call continue or break in the enclosing > context.

This would differ with the break/continue used in other loops. If you need to break from many loops, enclose them into a function and return from it !
