> In Groovy 3 we extended the method pointer to also work for a Class receiver and instance method. When used in this way, the method closure produced accepts an additional initial argument being the instance receiver. This works when supplied with a correct argument but gives an {{IllegalArgumentException}} instead of {{MissingMethodException}} when an illegal argument is supplied. E.g.:
> {code}
> class Y {
>   def m() {1}
> }
> ref = Y.&m
> assert ref(new Y()) == 1
> assert ref() == 1 // => java.lang.IllegalArgumentException: object is not an instance of declaring class [Should just be missing method exception?]
> assert ref(1) == 1 // => java.lang.IllegalArgumentException: object is not an instance of declaring class [Should just be missing method exception?]
> {code}
