Missing "could be written as"

There are some lints missing a "could be written as".
If I am on a clippy page, like manual_memcpy, I really like to not just see what is wrong in the example but also see how to fix the example.

Is there an interest in adding some more "could be written as" like in #4404 ?

I would be happy to fill some PRs for this :)

Yes, that would be really nice to have! In fact, it's already part of the 'Adding Lints' docs here, but could probably be highlighted in a sentence below, too.
