A modern programming language that makes developers happier.

kotlinlang

Hello! If I have a function that takes a callback that is called with a parameter, and for some callback I do not need or use this parameter – the only way to not get warnings about this is to use a @Suppress annotation, is this correct?
```fun myCallback(@Suppress("UNUSED_PARAMETER") someValue: Int) { }```

It seems I can only use `_` in a lambda...

<@UP5818NJK> that thing is really long and ugly, so potentially an alternative is to write a function, named whatever you want, that's generic and takes an argument, and uses that suppress directive

Then you can suppress warnings by calling the noop function

Right! Yes, I agree that it's ugly. That's a pragmatic suggestion, if there are no better language constructs for this – I was surprised that you couldn't use `_` in this situation.

I now did this simple thing:
```fun Any.ignore() {}```
Thanks for the suggestion!
