:wave: Hi, I'm trying to find a way to mix enum option using `multiple()` and `prompt()` to allow the user to provide values at runtime if nothing is provided.
Unfortunately, this does not seem to be supported.
What would be the recommended way to support this kind of behavior?

I'm currently using this, but this prevent me from using a prompt
```val flavors: Set&lt;Flavor&gt; by option("-f", "--flavors")
    .enum&lt;Flavor&gt;(ignoreCase = true)
    .multiple(default = listOf(Main)).unique()```


That particular combo isn't built in, but you can do it yourself easily.

`mutliple` is just `transformAll { it }`, and `prompt` is just `transformAll { it.lastOrNull() ?: terminal.prompt("") }`, so you can combine them like `option().enum<>().transformAll { it.ifEmpty { listOf(terminal.prompt("..."))} }`

Interesting, I'll try that. Thanks a lot.
btw, that is an awesome lib that you built :awesome:

I'm missing an import resolution on a `getValue` ReadOnlyProperty :thinking_face:

My bad, I forgot to convert it back to a `Set` :+1:
