// for parameterless matchers.

// We want to make sure that the user cannot set a parameterless expectation on
// overloaded methods, including methods which are overloaded on const. Example:
//
//   class MockClass {
//     MOCK_METHOD0(GetName, string&());
//     MOCK_CONST_METHOD0(GetName, const string&());
//   };
//
//   TEST() {
//     // This should be an error, as it's not clear which overload is expected.
//     EXPECT_CALL(mock, GetName).WillOnce(ReturnRef(value));
//   }
//
// Here are the generated expectation-setter methods:
//
//   class MockClass {
//     // Overload 1
//     MockSpec<string&()> gmock_GetName() { ... }
//     // Overload 2. Declared const so that the compiler will generate an
//     // error when trying to resolve between this and overload 4 in
//     // 'gmock_GetName(WithoutMatchers(), nullptr)'.
//     MockSpec<string&()> gmock_GetName(
//         const WithoutMatchers&, const Function<string&()>*) const {
//       // Removes const from this, calls overload 1
//       return AdjustConstness_(this)->gmock_GetName();
//     }
//
//     // Overload 3
//     const string& gmock_GetName() const { ... }
//     // Overload 4
//     MockSpec<const string&()> gmock_GetName(
//         const WithoutMatchers&, const Function<const string&()>*) const {
//       // Does not remove const, calls overload 3
