      Description

      The following works...

      class T {
             def doIt() { true }
      }
      
      def t = new T()
      
      assert t.doIt()
      t.metaClass.doIt = { -> false }
      assert !t.doIt()
      

      But this fails...

      interface I {
             def doIt()
      }
      
      class T implements I {
             def doIt() { true }
      }
      
      def t = new T()
      
      assert t.doIt()
      t.metaClass.doIt = { -> false }
      assert !t.doIt()
