      Description

      It seems that in Groovy, the increment/decrement operator is not only allowed
      on variables, but also on values. Here is a script that compiles without
      problems:

      def x = 0
      println(id(x)++)
      
      def id(x) { x }
      

      However, at runtime I get:
      Caught: java.lang.VerifyError: (class: IncTest, method: run signature:
      ()Ljava/lang/Object Incompatible object argument for function call
