If all the suspension calls in a suspend function were "hidden" under the for-convention (iterator/next/hasNext) calls, control-flow didn't find them, thus supposing that there is no suspension points and there is no need to generate a coroutine state machine The solution is to add relevant calls to CFG #KT-15824 Fixed
