I've run into a use case where I'd like to use a mapped_iterator to iterator the 1st (or 2nd) items in a sequence of std::pairs. Does select1st/select2nd exist somewhere within LLVM or is there some equivalent? If not, I'll add it. -Dave

I'm talking about mapped iterator + select1st. -Chris On Jul 16, 2011, at 2:58 PM, greened at obbligato.org (David A.

Dear testers, 5.0.0-rc3 was just tagged. This is a release candidate in the real sense: if nothing bad comes up in testing, this is what the release is going to look like. Please build, test and upload binaries to the sftp (use the /data/testers-uploads/ directory) and let me know what issues remain. I know we're a little bit behind schedule, but hopefully we can get to 'final'
