You don't need the `'_` here.

I still think we're missing a `impl<T: Release> Release for &T`.

And maybe a closure design is better, depending on how much code is
usually run in `release`, if it's a lot, then we should use the trait
design. If it's only 1-5 lines, then a closure would also be fine. I
don't have a strong preference, but if it's mostly one liners, then
closures would be better.

If you keep the trait design & we resolve the `&T: Release` question:
