//
// Foo(1);
// Foo(2);
// Bar("a") is called by which call to Foo().
//
// MockFunction<F> can also be used to exercise code that accepts
-// std::function<F> callbacks. To do so, use AsStdFunction() method
-// to create std::function proxy forwarding to original object's Call.
-// Example:
+// std::function<internal::SignatureOfT<F>> callbacks. To do so, use
+// AsStdFunction() method to create std::function proxy forwarding to
+// original object's Call. Example:
//
// TEST(FooTest, RunsCallbackWithBarArgument) {
// MockFunction<int(string)> callback;
// EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
// Foo(callback.AsStdFunction());
// }
+//
+// The internal::SignatureOfT<F> indirection allows to use other types
+// than just function signature type. This is typically useful when
+// providing a mock for a predefined std::function type. Example:
+//
+// using FilterPredicate = std::function<bool(string)>;
+// void MyFilterAlgorithm(FilterPredicate predicate);
+//
+// TEST(FooTest, FilterPredicateAlwaysAccepts) {
+// MockFunction<FilterPredicate> predicateMock;
+// EXPECT_CALL(predicateMock, Call(_)).WillRepeatedly(Return(true));
+// MyFilterAlgorithm(predicateMock.AsStdFunction());
