How do you access a Companion from Groovy?

class Foo {
  companion object {
  val s = "foo"
  }
}

results into Foo.Companion.s but the static field Companion clashes with the class Companion resulting in Companion::class.s and an unresolved member s due Groovy class syntax.

What kind of magic is this? 😄

But yes, it does work, thank you!

The .@ in Groovy means "access the field with that name directly".
If you for example have a property that consist of a field "foo" and a getter "getFoo", then in Groovy using .foo will call the getFoo getter, but with .@foo you can directly access the field without going through the getter.
Same works here for the companion object to access the static field called Companion instead of the nested class called Companion.

Thanks for the explanation. Don't know why I did found it when I tried to duckduckgo it... Interesting Foo.Companion.s does work when you don't use CompileStatic, but I want to enable it.
