Technically speaking, how would you create your own custom compile target(for example C#)? I mean you should be able to create your own since it is built using Gradle.
I generally don’t know, but I guess you would have to fork the Kotlin compiler. But that doesn’t sound like easy thing to do. It is more like several months of work for a team of several people.
I recommend joining the Kotlin Slack’s #python channel: this is exactly what they are trying to do. However, I believe this is currently on pause because of lack of time.
