Compatibility with Kotlin 1.5.0-RC. Long vs Duration

[turansky]

Current signatures:

public suspend fun <T> withTimeout(timeMillis: Long, block: suspend CoroutineScope.() -> T): T
public suspend fun <T> withTimeout(timeout: Duration, block: suspend CoroutineScope.() -> T): T

Method call with Long parameter works fine

Method call with Duration produce error:

java.lang.NoSuchMethodError: 'java.lang.Object kotlinx.coroutines.TimeoutKt.withTimeout-lwyi7ZQ(long, kotlin.jvm.functions.Function2, kotlin.coroutines.Continuation)'

But in that case, you had to get an experimentality warning: library authors shouldn't provide stable API that internally depends on experimental inline classes or other experimental API. If you didn't get the warning, I suggest filing an issue in the corresponding projecs.

It's experimental API :)

We'll release version 1.5.0 right after the release of Kotlin 1.5.0.

Such incompatibilities is the reason these functions are experimental right now
