it seems that `CoroutineScheduler` uses `require` that uses kotlinlang #announcements

it seems that

CoroutineScheduler

uses

require

that uses

contract

which is experimental

Contracts in stdlib (incl

require

) are a stable feature of Kotlin 1.3. Defining contracts for your own libraries is experimental.

However, we do use other experimental and internal features in implementation details of our libraries (where that would not affect their stable public API)

@elizarov so, Contracts are stable for internals usage, but not to external?

Yes. Contract specification language is not stable as well as some things related to evolution, compatibility, etc. It is easier for stdlib. Even if contracts get removed, their effect on stdlib functions will stay (it is a stable part of Kotlin language now)
