Yes, I've seen this in rb_include_module. But if you look at *my*
stupid.rb in the previous message :), you'll see that after extending
object with B and C, I can't reach neither of A methods. So
effectively A is not object's ancestor anymore. Is there any way to
#unextend A from the object so I could #extend it with A again? I
tried to use #remove_const to no avail.
