Yup, we didn’t yet update to Ratio 3.0, because we use it in many places and we’d have to do it all at once, so it’s not just a matter of bumping the version 
I generally agree that operator overloading is confusing when applied to things like dates, but when it comes to numbers, well, these operators were created for handling numbers. Not using operators makes things twice as less readable and adds the risk that someone accidentally uses > instead of Ratio.gt. Regarding performance, I don’t think that the difference between integers and rationals would be that crucial to make it always visible for developers. They are not tensors after all And the compiler still has to check for integers and floats upon each operation.
