The behavior of the Self type in the Extract struct from enum variant option is not as expected

Source code

enum Foo {
    Bar { node: Box<Self> },
    Nil,
}

fn main() {}

in line2 column5 use Extract struct from enum variant

struct Bar{ node: Box<Self> }

enum Foo {
    Bar(Bar),
    Nil,
}

fn main() {}

Expected

struct Bar { node: Box<Foo> }

enum Foo {
    Bar(Bar),
    Nil,
}

fn main() {}

Lines 128 to 134 in 85fb463

	fn extract_field_list_if_applicable(
	variant: &ast::Variant,
	) -> Option<Either<ast::RecordFieldList, ast::TupleFieldList>> {
	match variant.kind() {
	ast::StructKind::Record(field_list) if field_list.fields().next().is_some() => {
	Some(Either::Left(field_list))
	}

I'll take a try, @rustbot claim
