All i can say is that I've been using Clone ever since Jeffa pointed it out to me at (jeffa) Re: Deepcopy of complex structures. and I benchmarked it at Re: Deepcopy of complex structures. (resolved) and found it to be so vastly more efficient. Since then, it's been an indispensible part of my toolkit that I use and itjust works.

That's about as high a recommendation as I can give. I'm not shy of building deep and complex data structures, including thise that contain bless refs, and internal cross-references, and my confidence in doing so comes not in small part from the knowledge that when I need to copy them clone will "just do it", simply and efficently. I treat it like it was a built-in function and (so far) it's never let me down.

Many thanks to you for making the module available. It gets my highest approval rating -- I use it regularly without needing to look at the documentation. It is an integral part of perl as far as I am concerned.
