### Type erasure in the `PredicateMatcher`
Currently, the `PredicateMatcher` uses `std::function` for type erasure,
so that type of the matcher is always `PredicateMatcher<T>`, regardless
of the type of the predicate. Because of the high compilation overhead
of `std::function`, and the fact that the type erasure is used only rarely,
`PredicateMatcher` will no longer be type erased in the future. Instead,
the predicate type will be made part of the PredicateMatcher's type.
