builder error: when using selector expression on expression (missing autoderef in method?)

[ttytm]

Describe the bug

struct Foo {
	str string
}

// fn (f Foo) foo(f2 Foo) string { // would work, since no autoref when not mut?
// fn (f &Foo) foo(f2 Foo) string { // same error
fn (mut f Foo) foo(f2 Foo) string {
	return if f.str != '' { f } else { f2 }.str
	// return if f.str != '' { *f } else { f2 }.str // currently a manual deref is required
}

fn main() {
	mut foo := Foo{}
	dump(foo.foo(Foo{str: 'a'}))
}
