Expand description

This specialization trait is a workaround for LLVM not currently (2023-01) being able to optimize this itself, even though Alive confirms that it would be legal to do so: https://github.com/llvm/llvm-project/issues/52622

Once that’s fixed, Option should go back to deriving PartialEq, as it used to do before https://github.com/rust-lang/rust/pull/103556.
