11/26/2018, 2:42 PMYou can have the extension function be just a thin "helper wrapper" around an

11/26/2018, 2:42 PMThat way you don't have to expose anything on the class

11/26/2018, 2:49 PMtechnically speaking, you may be able to implement the curiously recurring template pattern here, since you need a few classes to implement this behavior

11/26/2018, 3:05 PMyou can do it without an extension function.
Copy code
class Foo {
fun foo(block: Foo.() -> Unit) = this.block()
}d

11/26/2018, 3:17 PMI just wanted to point out that its possible to do it without an extension method. If subclasses are involved, he could override the method in the subclass
