I have only used Kotlin in the context of Android so far, and like the language — I wish Java had many of these features — but almost find it more of a pain in the ass than its worth for reasons like this (kapt). At some point, the build times get so bad I asked myself, am I being more productive having neat language features X,Y,Z or having 15sec build times (already too long) vs 2 minute build times (unbearable). Its like going from REPL driven development to something else.
