The question states:
Replacing the implementation of deref with self.as_ref() results in a stack overflow when running an unoptimized version. Why? (Hint: deref coercion)
But actually self.as_ref() does not cause stack overflow: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=9ce74e7edda0542dbf20c04f521b2879.
self.as_ref()
