Early definitions are a bit unwieldy, there are limitations as to what can appear and what can be referenced in an early definitions block, and they don't compose as well as lazy vals: but if a lazy val is undesirable, they present another option. They are specified in SLS 5.1.6.

Note that early definitions are deprecated in Scala 2.13 and will be removed in 2.14; they will be replaced by trait parameters in 3.0. This option is not recommended if future compatibility is a concern.
