@julienviet I see few issues so far:

- mutable/immutable collections (with no context I don't know what kind of collection should I create emptyList() vs mutableListOf())
- val vs var (don't know should I generate mutable variable or final)
- type inference (don't know when I have to generate type arguments or not: emptyList() vs emptyList<String>())
