...provided by Boost.Iterators. First problem is that inst_iterator (and actually InstIterator class template) is not Assignable, because it has a reference data member, while standard requires all iterators to be assignable. Second InstIterator is not DefaultConstructile, which is required from Forwarditerator. Also, I get error because InstIterator::difference_type is not signed integer type (its defined as unsigned), but in this case the current standard does not say it's should be signed, though it looks reasonable and proposal for new version of standard require that. > > > Probably...
