In case anyone missed the planned cold-streams work explanation: https://github.com/Kotlin/kotlinx.coroutines/issues/254#issuecomment-408379789

Well, I guess it might work for filter:

fun <Src, SrcElement> Src.filter(): Src
        where Src : Source<SrcElement>,

But not for map. The type system has no way (that i know of) to say two types must be equal except for their type parameter.

fun <Dst, Src, SrcElement, DstElement> Src.map(): Dst
        where Src : Source<SrcElement>,
              Dst : Source<DstElement> // <-- We can not express that Src and Dst must be the same generic type, except for their type parameter :-(
