I'm not sure what is the best way to document this. Ah - I finally see. Sorry to be so dense. Perhaps the way to do it is you document Object#dup and #clone, highlighting the differences as you did in your previous e-mail, and then at the bottom of each description say "This method may have class-specific behavior. If so, that behavior will be documented under the #init_copy method of the class." Cheers Dave
