@nkiesel you shouldn't get any unused parameter warnings on either

main

or implemented interface methods, even if you don't rename them to

_

@yole: yeah, but I still have to review the whole implementation before I know that they are really unused. yes, I could add a comment (or an annotation) to the parameter, but that is a hack in my book.

or put a caret on the parameter in your IDE

my IDE is more often than not Emacs, or code review page in Github/Gitlab/ReviewBoard, or a

less *.kt
