No, it was right before. The "flow" of information is always a -> b, otherwise the profunctor instance wouldn't work.

I'm not sure what the example is referring to. ObjectSchema is actually used all the time, because it's the argument of object.

I don't think codec supports swagger. There are other libraries that do, but they weren't available when I wrote this. Also now that we have written this library, tailored it to our use case and adapted all our code, what would even be the point of using something else? And why write it here as a TODO instead of just writing a comment or asking me directly?
