how do i indicate that a function type as a parameter is optional.

Copy code

internal fun getFoo(block: (Foo.() -> Unit)): Foo {
  return Foo().apply{
    //someinit
  }.apply{
    block()
  }
…
}

right now if i don’t have actual functionality to include in the block i have to call it like:

getFoo{}

is there a way to allow calling it like

getFoo()

in this case?
