C++ zero-cost varargs foreach - reduce code duplication while keeping the code expressive

foreach.h

// Written by Cameron Reuschel (XDracam), 2019
//
// Does not work on MSVC, since they use a different preprocessor algorithm than clang and gcc.
// Use like this:
//   foreach(const &, myFoo1, myFoo2, myFoo3, _.foo());
//   foreach(&&, a, b, c, sum += _);
