 3. Inline methods can also be abstract. An abstract inline method can be implemented only by other inline methods. It cannot be invoked directly:
-```scala
-abstract class A {
-  inline def f(): Int
-}
-object B extends A {
-  inline def f(): Int = 22
-}
-B.f()         // OK
-val a: A = B
-a.f()         // error: cannot inline f() in A.
