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svn sandbox seemed to be outdated.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. 

Rgds
