/** A predicate which determines whether a given [[Term.Select]] appearing in the Scala source file,
 * has an `apply()` method (whether defined implicitly or explicitly).

 * This is true of all case classes and functions, and also some companion objects.

 * The framework will use this in order to properly identify invocations where the `apply()`
 * does not appear explicitly.
