I have a map that’s of type VertxHttpHeaders. That’s a type that implements Iterable<Map.Entry<String, String>> but it does not implement Map. I want to filter out some headers and get back a Map. This is what I’ve come up with:

headers
    .map { it.toPair() }
    .toMap()
    .filterKeys { noCopyHeaders.contains(it).not() }

Can I do better somehow? 🙂 I wish I didn’t have to do the two-step conversion to the map and I wish I had a `filterNotKeys`… I guess I could just add those as extensions

headers.associate { it.toPair() }
    .filterKeys { noCopyHeaders.contains(it).not() }

Oh, nice!
