re: Hey, builder pattern is interesting.... I'm trying to understand this expression: fun dialog(init: DialogBuilder.() -> Unit): Dialog = Dia...

So actually the builder pattern is integrated in Kotlin itself.

Given data class User(val id: Int = 1, val name: String = "")
Then this do the same as the builder pattern would do in Java
val user = User(name = "Alejandro", id =42)

The dialog function is a building block for building a DSL.
It takes as parameter a function init that you could define as having a parameter DialogBuilder and returning Unit. But instead you define the parameter as an extension function of DialogBuilder.
