I did not hear that Nim made ORC the default, thanks for that! I still think that my overall point stands: sure, you can treat this as an optimization pass, but that kind of overhead isn't acceptable in the C++/Rust world. And syntax is how you communicate programmer intent, to resolve the sorts of ambiguous cases described in some other comments here. I am again reminded of escape analysis https://steveklabnik.com/writing/borrow-checking-escape-analysis-and-the-generational-hypothesis/ https://steveklabnik.com/writing/borrow-checking-escape-anal...
