// This is almost guaranteed to trip someone up sooner or later, as the reason why
// below two matchers aren't equal is not obvious at first glance.
//
// If a parameterized custom matcher only provides a predicate (delegate) but no
// render expression, how do we get at the parameters in order to compare them?
// Short answer: They typically sit on the delegate's target object, which we'd have
// to compare for structural equality. Which is is kind of expensive.
//
// So for the moment, this ambiguity is left unresolved. If you run into this, the
// easiest way to work around it is to provide a render expression to `Match.Create`.
