Scala early initializer

In Scala, what is an "early initializer"? - Stack Overflow

Early initializers are part of the constructor of a subclass that is intended to run before its superclass. For example:

Dropped: Early Initializers

Early initializers of the form

code:python

class C extends { ... } with SuperClass ...

have been dropped. They were rarely used, and mostly to compensate for the lack of trait parameters, which are now directly supported in Dotty.

trait Parameters を代わりに使えということっぽいが
