/**
 * @assertion It is a compile-time error if a built-in identifier is
 * used as the declared name of a class, type parameter or type alias.
 * @description  Checks that it is not a compile-time error by itself when a built-in identifier
 * is used in an identifier reference, but since no declaration with that name can exist, lookup
 * fails eventually with the type of error depending on context. This test checks that in a class
 * instance scope, referencing a built-in identifier results in NoSuchMethodError as long
 * as the identifier is placed in such a way that it cannot be mistaken for another token.
