When designing a DSL, is it possible to use a lambda to collect list inputs? I have not been able to find a way to make it work.

What I want:

dependsOn {
  "foo"
  "bar"
  "baz"
}

and then I can "collect" the 3 as a list.

What I ended up doing for now is:

dependsOn {
  add("foo")
  add("bar")
  add("baz")
}

And the definition looks like:

fun dependsOn(init: MutableList<String>.() -> Unit)

Is there a better way to do this, such that I don't need the add(...)?

You could overload the plus operator. The HTML dsl does this for the string content of a tag

Its a little closer
