Function enum_kind 

fn enum_kind(
    value: &Bound<'_, PyAny>,
    dotted: &str,
) -> Result<MemberKind, Error>

Reads an enum class’s mixin type and its members.

The values are rendered with Python’s repr, which is what a stub writes for a literal default anywhere else in this file, and literal then refuses anything that is not a plain literal — so an enum over some non-literal value stops the run instead of putting an address in a committed file.
