listOf(1, 2, 3).map { Unit }

IDE marks

Unit

as redundant and proposes to replace it with:

listOf(1, 2, 3).map { }

How do you handle this? Proposed fix looks weird to me. This issue occurs quite often in RxJava streams

whats the point of doing that ? i dont get it but may be you want

List(3) { Unit }

I've done similar things with RxJava like streams. I've just become accustomed to empty braces meaning unit. Other option is to create an extension methods

mapToUnit

. Then the odd code is only in one place.

oh ok i missed that last phrase i see... the estension method seems like a good alternative to me 👍

Proposed fix looks weird to me.

I add comment in the body of map, though, I would prefer if it would be fixed and { Unit } wouldn’t be marked as warning
