Paul King commented on GROOVY-12297:
------------------------------------
Should be fixed (for non-raw) Tuples/Lists from 6.0.0-alpha-1 as part of GEP-20.
> STC: multi-assignment works with Tuple-returning methods on the RHS but not
> with List-returning methods
> -------------------------------------------------------------------------------------------------------
>
> Key: GROOVY-12297
> URL: https://issues.apache.org/jira/browse/GROOVY-12297
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 5.0.3
> Reporter: Björn Kautler
> Priority: Major
>
> 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.
