I don't think mod2 is nested in mod1, in any sense. There's no reason 
for ruby to keep track of the modules that are created during the 
execution of the block that accompanies the mod1.module_eval call and to 
associate them with mod1. The only reason B is associated with A in

module A
   module B; end
end

is that they are lexically related. (More precisely the constant "B" is 
in the namespace belonging to the class A.)

Maybe someone else has a more definitive answer?
