when writing a Kotlin DSL, is there a better way of having a lambda accept a list of enums than using the "plus" overloading technique like this?
With the unary plus technique, you end up w/ DSL code that looks like:
authMethod {
  +PIN
  +CHIP
}
but it'd be nice to remove the '+' prefix

what exactly would you rather this look like

like you can’t really get rid of the `+` - you could replace it with some other operator, but you can’t really have a bare list here

maybe if you wrote an overload that took `() -&gt; List&lt;AllowedMethodType&gt;`

```
authMethod { listOf(
  PIN,
  CHIP
)}
```

but I don’t know if that’s much better

Wanted a bare list.  Yep, tried the listof already.  I have an assignment method too so you can pass a list in.

You can provide a lambda receiver that has `operator fun invoke` for the target types so you use `()` instead
