Description

As one core meta-programming feature from ruby is enhancing of existing classes, or even the creation of anonymous new ones, I'm wondering whether this is possible already. Something like:

module Ext
  def foo;end
end

class A
  def self.enhance
    Class.new(self) do
      include Ext
    end
  end
end

How could one type the result of calling .enhance?

Research direction

The issue provides no file or test entry point; start with the Ruby example using Class.new(self) and include Ext. Determine how, or whether, RBS can type the result of A.enhance, and consider the seven-comment discussion before defining what a supported solution would mean.
