A slightly more fluent version of MustHaveHappend(Repeated.Exactly(times)). For https://github.com/FakeItEasy/FakeItEasy/issues/354

IntTimesExtensions.cs

// Allows
//   A.CallTo(() => fake.Add(A<object>._))
//    .MustHaveHappened(2.Times());
//
// but then the ints all have a Times method on them.

MustHaveHappenedIntExtensions.cs

// Allows
