I find the "expectation" terminology to be confusing here - it took me a little bit to understand what that would mean in terms of concrete changes to the source. I don't have any better suggestions though.

Changed the wording to
= help: change the expected type to be function pointer `fn(isize) -> isize`
= help: if the expected type is due to type inference, cast the expected `fn` to a function pointer: `foo::<u8> as fn(isize) -> isize`
