e: java.lang.IllegalStateException: Backend Internal error: Exception during code generation
All I did was update this repo: https://github.com/Zhuinden/compose-simple-stack-experiment to dev04 and then remove 
unaryPlus
from before where it was still there, and boom compilation exception in compiler 🤔
oh it's probably this:
Copy code
composeOptions {
        kotlinCompilerExtensionVersion "0.1.0-dev04"
    }
solved
