Ownership specifiers are rather awkward to work with

ideally, i would want to be able to just do

extension TypeA
{
    public consuming
    func finalizeMesh() -> TypeB
    {
        let a:[A] = consume self.a
        let b:[B] = consume self.b

        return .init(a: a, b: b, c: self.c, d: self.d)
    }
}

That should be possible once partial consumption support is implementation, or even:

  return .init(a: consume self.a, b: consume self.b, c: self.c, d: self.d)

with or without the explicit consumes.
