Is there going to be a backwards-compatible version of Prelude then? Maybe called something like SimplePrelude which could be imported to keep all old code working without any changes (it could also be used for teaching purposes then, because the old Prelude really is much easier to understand for beginners, I think). Or does this change break something fundamentally that makes this impossible?
