@Cykelero Ha, I’m still figuring most of that out. At the moment it means I can write code in the more expressive syntax, with enums, guards, complex switch statements, extensions. I still have to figure out collections, and don’t know how far I’ll go with protocols and generics. I won’t touch concurrency. I’ll rewrite one of my games with it and see if it’s actually useful or too much goofing around.
