Basically just always pass everything as "const"  (or "constref" if it's specifically a record) unless you literally can’t.

Yeah sounds like a bug but I’ll wait for one the compile guys to verify that.

I belive I was told that const doesn’t actually perform any optimizations but constref does (for structs yes). I hope that’s right because I don’t want to feel an urge to type “const” every time I write a function. Honestly I don’t think I’ve ever used const but just  started using constref last year when I learned about it for the first time (good feature when ever it was added).
