Re: [boost] [range] calling front() on iterator_range of const elements

Is it intentional that one can not call range.front() on an iterator range of const values?

#include <boost/range/iterator_range.hpp> int main() { typedef const char* iterator; iterator p = "test"; boost::iterator_range<iterator> range(p, p+1); range.front(); }

This fails to compile as value_type& front() const { ... return *m_Begin; } in iterator_range.hpp tries to bind a const char lvalue to a non const reference.

The same happens with back() and operator[].

The fix is to return typename std::iterator_traits<IteratorT>::reference and not value_type&

I believe this is fixed in cvs and rc_1.34 branch. -Thorsten
