We would like to understand extension functions a bit better. How does the compiler know they are available? We have a class transformer in place as part of our Gradle plugin, and after that step extensions functions raise compiler errors when used from another module. (Context: https://github.com/greenrobot/ObjectBox/issues/134)

make sure you’re not corrupting Kotlin’s

@Metadata

annotations

That's the only source for the Kotlin compiler? The actual classes with extension functions should not be transformed, but just copied on a file level. So `@Metadata`should be untouched. Can you think of another reason?

there are also

.kotlin_module

files, they should also be preserved

ah OK, will check
