could EnumIter be recursive ?

[VirgileHenry]

Would it be useful / meaningful to have the EnumIter to work recursively if enum data have this trait too ?
Something like :

`
#[derive(EnumIter)]

enum E1 {
A,
B,
}

#[derive(EnumIter)]
enum E2 {
C(E1)
}

for v in E2::iter() {
println!("{v:?}"); // C(A), C(B),
}
`
