Answer 1

I'm a Kotlin newbie (though not a newbie developer), I slightly extended answer from @bashor to something looks neater for keys which are valid Java identifiers, but still allows ones which aren't. I tested it with Kotlin 1.0.1.

@JsName("Object")
open class Object {
}

fun jsobject(init: dynamic.() -> Unit): dynamic {
    return Object().apply(init)
}

header = jsobject {
    validJavaIdentifier = 0.2
    this["content-type"] = "text/plain"
    this["content-length"] = 50
}
