yes :-) in particular, given
template< class T > struct value_type_of { typedef typename iterator_value<T>::type type; };
do I say
typedef string::iterator I; BOOST_BROKEN_COMPILER_TYPE_TRAITS_SPECIALIZATION( I );
No, you have to pass I's value_type. There's no way for the compiler to strip the pointer from I purely at compile-time. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
