Yes (but actually I haven't found any eigenclass definintions on the 
web, not even on http://eigenclass.org/)

They will respond to those methods (since THEIR class has been changed):

class A
     def meth1
     end
end

a=A.new

class A
     def meth2
     end
end

class A
     define_method :meth3 do
     end
end

a.meth2
a.meth3
