reply thanks. Sort of off topic but does foreach need access to iterator (and not const_iterator).. like i have class B deriving from private std::vector<int> i allow const_iterator but not iterator. I get compile time error.
FOREACH uses Boost.Range. If your type doesn't naturally meet the requirements for a range (and it sounds like it doesn't), you must hook Boost.Range's customization points.
