OK, thanks. I know about niches/elision and I didn't though Option<Infallible> as an example of Option<&T> and, backtracking, I was confused by "It does say that Option<&T> is the same size as &T," followed somewhere by "but there are definitely edge cases". I did mentioned I was maybe misinterpreting what followed that phrase.
