    map syntax

    been a long time since I've programmed in C++, and even longer since I've started a thread here. anywho:

    why is this ok:
    Code:
    std::map<std::string, std::map<std::string, std::string> > values;
    and this not:
    Code:
    std::map<std::string, std::map<std::string, std::list<std::string> > > values;

    What errors are you getting with that?
    "Owners of dogs will have noticed that, if you provide them with food and water and shelter and affection, they will think you are god. Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."
    -Christopher Hitchens

    Well, it compiles fine, so what's the problem?

    As long as I include list and string, it compiles fine.
