+1 on what @bkietz said: the casting behavior should be declared on the operation, not on the type itself. Ideally we would have a declarative way of defining more elaborate type constraints on kernels and a decidable solver that dispatches to the appropriate implementation. If we implement that we have to write a checker that ensures there is always only one solution (ordering of declaration of the kernel implementations shouldn't matter). -- This is an automated message from the Apache Git Service.
