alt Hacker Newsbtw. That could actually make it slower to compile. The compiler uses the orphan rule to short circuit some checks IIRC.
Nevertheless, people in the project are trying to figuring out a way to relax the rule while still maintaining coherence, so this might happen some day.
there are good reasons, obviously, but it's my #1 PITA, #2 is comptime type introspection (it looks like @yara-blue is making some progress, so fingers crossed)
BTW: cheers, we should grab a beer some day :)
