[Boost-users] range_ex

Hi list, what's the status of range_ex? I read that it was accepted into boost half a year ago. So, will it make it into 1.41? This week I downloaded it from the boost vault, as the version from the svn sandbox seemed to be outdated. I like it very much so far. Just two remarks/questions: - in my measurements using the piped adapters (filtered / transformed) was on average 4% slower than hand coded loops. Do I have to live with that, or are there any tricks / hints? - I can't use lambdas for the adapters. - transformed expects a result_type that also lambda::res<> doesn't seem to provide. - filtered tries to copy the functor, which in turn lambda doesn't seem to like.
