@swiftcoder Ah. Well, both?
`super let a = Thing;` makes `a` live as long as the surrounding block. The lifetime that allows the block's final expression to be `&a`, basically.
On top of that, we still have temporary lifetime extension, just like we have in a regular `let`:
`let a = &temp();` makes the temporary life as long as `a`.
Same for `super let a = &temp();`: the temporary will live as long as `a` (which might live longer than it would have in a regular `let`).
