Sorry for keeping you waiting. I have not forgotten about it and I would very much like to put it to the next release.
I just haven't find a time to look into But I have it in my schedule before xmas.
Any chance we'll see _real_ predicates as well (i.e. starts_with etc that can be used with standard algorithms)?
std::find_if(v.begin(), v.end(), istarts_with("abcd"));
What you have shown is just a simple example of currying and there are at least two facilities in Boost that provide such a functionality. Namely Boost.Bind and Boost.Lambda. You can write something like this: std::find_if( vec.begin(), vec.end(), boost::bind<bool>(boost::istarts_with<std::string, std::string>, _1, "bc", std::locale())); It is not as nice as your example, but it works. I'm little bit reluctant to add something like this directly to the library. There are already quite a lot of variants of algorithms. Adding some more could be quite confusing. I would prefere to add some realy new functionality. But don't take this as a final 'no' from me. I'm open for discussion. Best regards, Pavol
