Hi, I've recently submitted a bunch of pull requests with cleanups for libcpp.string and libcpp.vector, most importantly fixing overloads taking and/or returning iterators and C++11 methods: https://github.com/cython/cython/pull/488 https://github.com/cython/cython/pull/489 I might also manage to take a look at set / map / pair which we likewise need for our projects, but it would be great to get some feedback from the core developers first. If the dominating opinion is that I'm strongly misguided in some way, I'd appreciate a short note before I invest more work into this :-) Many thanks! -- Sincerely yours, Yury V. Zaytsev
