 Have you noticed that a matcher is just a fancy predicate that also knows how to
 describe itself? Many existing algorithms take predicates as arguments (e.g.
 those defined in STL's `<algorithm>` header), and it would be a shame if gMock

 Luckily, you can use a matcher where a unary predicate functor is expected by
 wrapping it inside the `Matches()` function. For example,
