Not sure this was submitted by the original author. I forwarded a note to the repo owner pointing back here.

Any language right? Here's classic C++.

  #include <iostream>

  int main ()
  {
    std::cout << std::cin.rdbuf();
    return 0;
  }

C++ does include hash functions. Of course, most will just use std::unordered_map.
