I thought this would fail the stable-check, but it looks like the stable-check doesn't recurse into subdirectories. 😢 I will try to fix that some point in the future. Sorry this caused a hiccup! |

Given that we are rolling back stabilization of the never type, this example needs a feature gate. The test was added only recently, by @ehuss -- I think that ordinarily we don't document unstable features, but given that this section of the book seems to be older, and that
!can appear in some places, and that we hope to get!stabilized very soon, I opted not to remove it.This needs to land semi-urgently so that rust-lang/rust#67224 can land.
