I had assumed that context<ID,val,NEXT> was a dictionary with only 1 value for given ID. However, I guess there could be several entries where ID==skipper_tag and only the 1st one is retrieved by the context.get<ID_>(ID_) member function. I guess there's some method to pop the top value with given ID off the context stack. In that case, I've no idea how to solve the problem.
