I hope we'll also be able to follow a 5th direction, of allowing one to specify
a slice or a trait or a package that just adds an inst var to a class instead
of having to provide the whole class definition just to add an inst var.
We would love.
With Epicea we have Changes representing not only class and instance
addition/removal...
Now the question is also how do we initialize such new added instance
variable.
Now we have probably to recompile the full class hierarchy.
We are brainstorming on a modular way to initialize objects
What are the paths to achieve that in a clever way.
