actually my opinion is that coroutines makes promise and stream irrelevant for writing non blocking code, so kudos to Kotlin to provide such goodness

parsers are also a good use cases : here is an HTTP request parser written with coroutines https://github.com/vert-x3/vertx-lang-kotlin/blob/74e5bf75b1ffc215c15f1c26d516637bd58ac875/vertx-lang-kotlin-coroutine/src/test/kotlin/io/vertx/kotlin/coroutines/HttpParserTest.kt#L45
