The code has

template<typename InputStreamable>
  bool operator>>(InputStreamable &output);

template<typename Char, typename Traits, typename Allocator>
  bool operator>>(std::basic_string<Char, Traits, Allocator> &output);

This seems to require partial ordering. The second overload should probably
be replaced with

bool operator>>(std::string &output);

bool operator>>(std::wstring &output);

on deficient compilers.
