...Are there any programming languages that will let you define your own primitives? It seems like it could be useful, both for restricting what your code can do, and for allowing the compiler to optimize it better, but I don't know a ton about that kind of thing. :/
@Angle I think Lua does, but IIRC it isn't very good at it, and almost every library for Lua implements the same primitives in incompatible ways
@Angle Yeah, it's way worse. You get every library having its own incompatible classes and other structures
@Zauberin Pfft, okay that's a good argument against. I thought every library having it's own incompatible Vec3 was bad, but yeah that sounds waaaay worse. :/
