DelayedInit or OnCreate, any solution?

Language Design

@adriaanm I found a workaround for my issue.
Library code

package MyLib
trait Post
@scala.annotation.implicitAmbiguous("This definition may be called only post-construction")
implicit object GeneralPost extends Post

class Foo {
  implicit object ForceAmbiguity extends Post
  private lazy val _postConstruction = {
    //Something to be used once at Post-Construction
    0
  }

  def postConstruction(implicit post : Post) : Int = _postConstruction
}

User code

new Foo {}.postConstruction //compiles
new Foo {postConstruction} //Error: This definition may be called only post-construction

So all public members that must be called post-construction must have a Post implicit (so the implicit also helps to document the constraint for the member).

What do you think?
