    > Or, we could decide that parameterized methods do not, in fact, implement
      interfaces, but then it's much less clear why we need methods at all. If

      parameterized function.
    
    > So while parameterized methods seem clearly useful at first glance, we
      would have to decide what they mean and how to implement that.
