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
