// To generate bind.h from bind.h.pump, execute:
// /home/build/google3/third_party/gtest/scripts/pump.py bind.h.pump

// Bind() is an overloaded function that converts method calls into function
// objects (aka functors). It captures any arguments to the method by value
// when Bind is called, producing a stateful, nullary function object. Care
// should be taken about the lifetime of objects captured by Bind(); the
// returned functor knows nothing about the lifetime of the method's object or
// any arguments passed by pointer, and calling the functor with a destroyed
// object will surely do bad things.
//
// Example usage:
//   struct Foo {
//     int Test1() { return 42; }
//     int Test2() const { return 52; }
//     int Test3(int x) { return x*x; }
//     float Test4(int x, float y) { return x + y; }
//   };
//
//   int main() {
//     Foo foo;
//     cout << talk_base::Bind(&Foo::Test1, &foo)() << endl;
//     cout << talk_base::Bind(&Foo::Test2, &foo)() << endl;
//     cout << talk_base::Bind(&Foo::Test3, &foo, 3)() << endl;
//     cout << talk_base::Bind(&Foo::Test4, &foo, 7, 8.5f)() << endl;
//   }
