Hello guys, I was exploring kotlin coroutines source code and I found a lot of unused imports. Is this intentionally? or it would be OK if I submit a PR to remove them?

It depends. Can you give an example?

like

import kotlinx.coroutines.internal.*
import kotlin.coroutines.*

in

ThreadPoolDispatcher
