Little things make a big difference

Of all the cool features I've read about that are in c++20, the one I find myself wishing for most often is the spaceship operator.

Sure concepts sound great, and improve the improvements to constexpr are going to make a big difference, but I write more class comparators than code that will be helped by those things. And it's almost all annoying boiler plate (which is why the spaceship opperator is a thing, after all).
