If `no_restriction()` were to use `&T` instead of `&()` as an argument, the
compiler would have added an implied bound [implied
bound](https://rust-lang.github.io/rfcs/2089-implied-bounds.html), causing this

This error can be resolved by explicitly naming the elided lifetime for `x` and
then explicily requiring that the generic parameter `T` outlives that lifetime:
