context. In other cases, e.g. in S… two variants: one when elementFunction is synchronous (blue) and one when it’s asynchronous (red). And indeed, for example Kotlin’s coroutines introduce a second forEach implementation so that it works both in normal and coroutine context. In other cases, e.g. in Scala’s async/await,…

That is not the case. Kotlin coroutines are not colorless, but they do elegantly solve most of the red/blue problems. In particular, Kotlin collection functions like forEach do not have a second implementation. A single implementation works equally well both for synchronous and asynchronous cases.
