 * Inner classes are included because they are accessible from a value of the outer class. For example:
 *
 * ```
 * class Outer {
 *     inner class Inner
 * }
 *
 * fun foo() {
 *     val outer = Outer()
 *     outer.Inner()
 * }
 * ```
 *
 * While Kotlin always expects a constructor call when accessing `outer.Inner`, it nonetheless requires inner classes to be contained in
 * non-static scopes.
