Required multiple arguments doesn't work

[tersers]

Say I have an argument as follows:

private val urls: List<String> by argument("urls", help="Some list of URLs.").multiple(true)

No exception is thrown when the argument is not provided in the CLI. I believe an exception should definitely be thrown in this case. Is there something I'm missing or is this a bug?

Thanks :)

Yep, that's a bug. Thanks for the report!
