Ah, I ported that to dotty a while ago but then completely forgot to follow-up on the issues I found: Commits · smarter/twitter-util · GitHub
I’m on it: `@throws` annotation not working · Issue #8593 · lampepfl/dotty · GitHub
Yeah we need to do something here, I think import scala.language.reflectiveCalls should be interpreted by dotty to treat structural types the same way scala 2 does.
Dotty doesn’t implement support for Manifest, I think we could but I’d rather let it die finally.
