deprecate nested "overriding" classes with same name #8353
Description
Martin says:
In dotty I propose to no longer allow nested classes with the same name which shadow each other. It's less convenient that way, but a lot safer.
instead of:
trait Core extends Base {
class Status
}
trait Ext extends Core {
class Status extends super.Status
}write:
trait Core extends Base {
class Status
}
trait Ext extends Core {
class StatusExt extends Status
}
