>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 5.0.3
>            Reporter: Björn Kautler
>            Priority: Major
>             Fix For: 6.0.0-alpha-1

> This does work under STC:
> {code}
> @groovy.transform.CompileStatic
> class Foo {
>   def foo() {
>     def (foo, bar) = bar()
>     println(foo)
>     println(bar)
>   }
>   Tuple2 bar() {
>     ["foo", "bar"] as Tuple2
>   }
> }
> new Foo().foo()
> {code}
> but this does cause a compilation error that only List or Tuple on the RHS are supported:
> {code}
> @groovy.transform.CompileStatic
> class Foo {
>   def foo() {
>     def (foo, bar) = bar()
>     println(foo)
>     println(bar)
>   }
>   List bar() {
>     ["foo", "bar"]
>   }
> }
> new Foo().foo()
> {code}
> Would be nice if also {{List}} would work here.
