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

[Cyril Find]

whats the point of doing that ?
i dont get it but may be you want List(3) { Unit }

This issue occurs quite often in RxJava streams

[arekolek]

For example I have some streams as input and I want to output Observable<Unit> after some transformations to the input

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 👍

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
