Replace the binary `Operation` interfaces with the `OperationWith(T:! type)` interfaces described in the design, and add a `Result` associated type for both unary and binary operations. Update the `impl`s in the prelude for integer types to use the new form, including supporting implicit conversion of either operand. I've tried to split this PR up into commits focused on distinct changes for review convenience. It may be simplest to review it one commit at a time.
