Didn't read the source material but I see the word "compiler"--Maybe a compiler plugin would do the trick? 😉

For a start... but I think there needs to be some kind of language or annotation support. So if you give a function x.pow(2) it would derive 2x with respect to x.

I think it is important for library creators, but not necessarily for normal developers. And nothing stops you from using those libraries from Kotlin/Native. Interoperability is nice.
