[Boost-users] [string algorithms] trim, functors

Hello. Could you answer these two questions: 1. Are there trim range algorithms that work with iterators, instead of strings? (I didn't find such). If not, why not to add them? Something like this: http://pastebin.org/146696 2. How can I use, for example, boost::algorithm::is_space() with standard functors? This: boost::not1(boost::algorithm::is_space()) doesn't work. It's enough to specialize boost::unary_traitsboost::algorithm::detail::is_classifiedF, but the fact that 'is_classifiedF' is in 'detail' namespace is a bit confusing. Is it ok to use it? Thanks.
