it's more complicated than that:

module M

   def Clobber
   end

   Const = 42

   def self.included other

     :nothing

   end

end


class C

   include M

end


if you want method lookup to behave like constant lookup this would  
*have* to inject the Clobber method into C.   this is not widely  
appreciated, but ruby injects the constants from a module into a class  
on inclusion *regardless* of any 'self.included' hook defined.  so to  
maintain consistency between methods and constants we'd have to either

A) have the above code cherry-pick caps methods and include them  
silently behind our backs

B) Not have constants injected during module inclusion

feels a bit like standing on an icy roof to me...
