Does program_options somehow support something like --base x=hello --base y=world where the parsed "--base"s will be put in a std::map<std::string, std::string> (or std::map<X,Y> in the general case?)

(At the moment I parse --base into a vector<string> and process the read strings after program_options has done its job.)

There's no such support presently - Volodya
