No - but exceptions (only) will get a special built-in clone mechanism
(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html) 

std::copy_exception will do the same thing that a clone member function
would do. The exception library could implement copy_exception (in part)
by searching a table of registered types for a match.
