Glad it helped. By the way, there's a module in the core distribution, Clone, which provides increased flexibility (it can handle datastructures of arbitrary shape) with its clone() function. However, it is actually considerably slower than even your first method. It's an example of where the increased abstraction that makes it a more useful tool all around also carries with it a performance impact.

diotalevi has (or had perhaps) a module on CPAN, Clone::Fast, but when I went to install it with cpan Clone::Fast, the cpan utility couldn't find it. I would like to have tried benchmarking it.

Another aside: Storable (also in the core distribution) offers dclone(), but according to the Clone documentation it's even slower, while being even more flexible.
