> If the case mentioned in https://docs.groovy-lang.org/latest/html/documentation/#_default_conflict_resolution used static methods instead of instance methods, "T.super.m()" disambiguation is not available.
> Consider the following:
> {code:groovy}
> trait A {
>   static m() { 'A' }
> }
> trait B {
>   static m() { 'B' }
> }
> class C implements A, B {
>   void test() {
>     print m() // prints "B"
>     print A.super.m() // java.lang.IllegalArgumentException or some other compiler problem
>     print B.super.m() // java.lang.IllegalArgumentException or some other compiler problem
>   }
> }
> new C().test()​
> {code}
