---------------------------------------------------------------

Tested with this code:
{code:groovy}
@groovy.transform.CompileStatic
static Tuple2<String,Integer> make() {
  new Tuple2<>("answer",42)
}

def (String mystr, Integer myint) = make()
println mystr
println myint
{code}

Prints "answer\n42\n".

Tested with this code:
{code:groovy}
@groovy.transform.CompileStatic
static Tuple2<String,Integer> dostuff() {
  new Tuple2<>("answer",42)
}

def (String mystr, Integer myint) = dostuff()

println mystr
println myint
{code}

Prints "answer\n42\n".

> @COmpileStatic seems to bomb with 2.4 if I have:
> 1) a static util function such as:
>     class blah {
>         static Tuple2<String,Integer> dostuff() { new Tuple2<>("string",55) }
>     }
> 2) invoke via:
> def (String mystr, Integer myint) = dostuff()
> With @CompileStatic, that all bombs.
> Alternatively, tried using getAt overrides, also did not work, but that would lack typing infor necessary for @CompileStatic. But the Tuple2 should have the necessary type info...
> I would think this could be done... I might try to do it, but I'd like to file the issue
