I would like to nominate `Option::as_deref` for the worst named method in Rust
-
oh I'd not thought of it like that: of course Option<T> could impl Deref with Target = Option<<T as Deref>::Target>, which wouldn't make Option<T> transparently equal to T under Deref, but I'd not considered the lifetime problem that requires GAT
Ironically you can almost implement this for `Option`, since null ptr optimization means that `&T == &Option<T>` in terms of layout. Except it's not particularly useful since that'd require `T: Sized`, meaning `Option<String>` couldn't impl `Deref`

wait is String not Sized

String is, `str` isn't

Concrete code to show what I mean https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=c3f925a354159bd379aa5abf15939600 …

oh right `where T::Target: Sized` is why String doesn't qualify
