Added proper "need 'this' to access member foo" errors instead of "variable foo not resolved" for some cases, added FIXME for the old error! Added a bit more information to the runtime's cyclic dependency detection exception.

    auto s = Cin.get();
    Cout("putting name").newline;
    Cout (s).newline;
