I want to remove ("undef") all methods, no only a single one. That is 
what I meant with "reset a class".

It is not exactly elegant, but indeed I think I won't need it often. I 
am inclined to using the "Object.send(:remove_const, :classname)" 
solution in both cases, reset and undef.

Thank you very much.
