The example code on handling JSON responses on https://vertx.io/docs/vertx-web-client/kotlin/#_handling_http_responses is syntactically incorrect in Kotlin.

client.get(8080, "myserver.mycompany.com", "/some-uri").as(BodyCodec.jsonObject()).send({ ar ->

client.get(8080, "myserver.mycompany.com", "/some-uri").`as`(BodyCodec.jsonObject()).send({ ar ->
