Yes, I think, because it's a part of constructing an empty object
and not concerned with content.

From Ruby 1.8, classes need not define their own #dup (or #clone)
methods.  The default methods (in Object via Kernel) embody the
functionality of DUPSETUP() / CLONESETUP(), then #initialize_copy
is invoked; here, you would copy across the specific T_DATA content.

Any recommendation of what to use to be backward/forward compatible
would have to come from those who know what's going on.
Some detail of your usage requirement might be useful to them.
