No `Enum` flag in the enum value type when mixing with some trait

[plokhotnyuk]

Having definition:

trait MyMarker

enum MyEnum(val value: String):
  case Marked extends MyEnum("marked") with MyMarker

I got Flags.EmptyFlags instead of Flags.Enum in the following call for:

TypeRepr.of[Marked].typeSymbol.flags

Marked is becomes a val case in the enum desugaring. This means that TypeRepr.of[Marked] or probably TypeRepr.of[Marked.type] is a TermRef. Therefore to get its symbol we need to use termSymbol instead of typeSymbol. The term symbol of Marked does contain the Enum flag.

Note that typeSymbol works in the simple cases because the val has a single class as a type and we can resolve the symbol. In this case we cannot resolve the type symbol because we have both MyEnum & MyMarker.

@nicolasstucki Thanks for the clear explanation!

Closing as not a bug.
