Support named tuple pattern

[oovm]

match term {
    case bind <- module::Name(ref a, mut b, c) if a > 0:
        body
}

Equivalent to:

let bind = term;
# Option<(?, ?, ?)>
let unapply = module::Name::extract(bind);
guard unapply.is_some() else {
    break;
}
# (?, ?, ?)
let bind = unapply!;
let a = unapply!.0;
let b = unapply!.1;
let c = unapply!.2;
guard a else {
    break;
}
body

If it is not a named tuple, omit the unapply process.

The same applies if the right hand side is a list
