How does this work (lambda after the String):

range {
    "age" {
        from = 10
        to = 20
    }
}

That "age" block is somehow creating a RangeBlock.RangeData instance.

Ah RangeBlock.RangeData provides an extension function on `String`:

operator fun String.invoke(init: RangeData.() -> Unit): RangeData {
        return RangeData(name = this).apply(init)
    }

That's a kinda nifty.
