So, what do people prefer (and why?):
template<typename InputIterator, typename V> bool none_of_equal ( InputIterator first, InputIterator last, V const &val ) { for ( ; first != last; ++first ) if ( val == *first ) return false; return true; }
or
template<typename InputIterator, > bool none_of_equal ( InputIterator first, InputIterator last, iterator_traits<InputIterator>::value_type const &val ) { for ( ; first != last; ++first ) if ( val == *first ) return false; return true; }
In the first case, I think there's (possible) conversion from V to iterator_traits<InputIterator>::value_type each time through the loop. In the second case, there is not.
Couldn't you provide both using SFINAE? Best, Vicente -- View this message in context: http://boost.2283326.n4.nabble.com/Boost-Algorithm-design-question-tp3876424... Sent from the Boost - Dev mailing list archive at Nabble.com.
