Scala 3: Completions, HOFs and aliased tuple types

[kubukoz]

Describe the bug

To reproduce:

1. Write this

//> using scala 3.5.0-RC5
trait Foo {
  def setup: List[Foo.Result]
}

object Foo {
  type Result = (String, String)

  def demo(foo: Foo) = {
    foo.setup.map<cursor>
  }

}

2. Get completions at <cursor>
3. See this:

Expected behavior

• No parenthesis around Result
• Wouldn't mind seeing the type alias's enclosing type name (Foo.Result) like in Scala 2

Operating system

macOS

Editor/Extension

VS Code

Version of Metals

v1.3.3

Extra context or search terms

• This is a really minor issue, arguably a cosmetic
• Opaque types don't have the parenthesis

Thanks for reporting! Looks like the first picture didn't upload, but I guess this about the added () around Foo.Result?

The type alias changes might have not been ported yet to Scala 3 repo.

Yes, sorry, I didn't notice after posting 😅 the completion in Scala 3 shows "(Result)" where 2.13 shows "Foo.Result".
