Currently (ruby 1.8.0 (2003-07-17 [i386-mswin32]) your example
does work like this.


---
class A; end
class B; end

class CrossPlatform
  class <<  self
    def unix
      def meth1;  p "u1" end
      def meth2;  p "u2" end
    end
  end

  def self.windows
    def meth1;  p "w1" end
    def meth2;  p "w2" end
  end

  def A.bla
    def meth3; p "A.bla" end
  end

  def bla
    def meth4; p "CrossPlatform.bla" end
  end
end


obj = B.new
CrossPlatform.windows
obj.meth1

CrossPlatform.unix
obj.meth2

A.bla
obj.meth3

A.new.meth3

CrossPlatform.new.bla
obj.meth4

"w1"
"u2"
"A.bla"
"A.bla"
"CrossPlatform.bla"
