Yes, pointed out, Clone is on the order of twice as fast as Storable.

In terms of the drawbacks, there have been some reports of core dumps when using Clone on some edge-case structures, although I've forgotten the details (it's certainly not common). Also, Storable provides a hook that lets objects participate in their cloning, so that the copied object can perform some kind of re-initialization or other post-cloning cleanup.

I've also posted a pure-Perl implementation to CPAN as Clone::PP, which is of course slower than either of the above.

And for those times where you don't really care how it's implemented, as long as you get a working deep-clone function, I've posted a generic facade called Clone::Any which will attempt to load Storable, Clone, or an equivalent module and will export the clone function from the first one it finds.
