Thanks. I can do that. (The thing I have in fact done, which works, is just not to use std::pair, and instead use my own type with operator SEXP defined.) However, it would be nice to also be able to wrap, e.g., std::set<std::pair<T, S>>, std::vector<std::vector<std::pair<T, S>>>, etc., just like one could do if it std::pair<T, S> was replaced by std::map<T, S> in these examples. It seems like this should theoretically be possible for std::pair, given that it works for std::map. However, I am not a template expert and have had trouble following the library code.
