      undefined template 'std::__1::array<std::__1::basic_string<char>, 10>'
    std::array<std::string, 10> keys = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9"};
/usr/include/c++/v1/__tuple:223:64: note:
      template is declared here
template <class _Tp, size_t _Size> struct _LIBCPP_TEMPLATE_VIS array;
                                                               ^
