 * This class actually contains three different rewriters depending on the kind of `Class.new` we ecounter:
 *
 * Assignments to a constant literal such as
 *
 *   A = Class.new(Parent) do
 *     ...
 *   end
 *
 * Are rewritten into
 *
 *   class A < Parent
 *     ...
 *   end
 *
 * Assignments to a non-constant literal such as
 *
 *   c = Class.new(Parent) do
 *     ...
 *   end
 *
 * Are rewritten into
 *
 *   c = Class.new(Parent)
 *     T.bind(self, T.class_of(Parent))
 *     ...
 *   end
 *
 * And sends such as
 *
 *   Class.new(Parent) do
 *     ...
 *   end
 *
 * Are rewritten into
 *
 *   Class.new(Parent)
 *     T.bind(self, T.class_of(Parent))
 *     ...
