use Storable qw(dclone);

Now, this simple deep_copy routine will break if there are recursive data pointers
(references that point to already seen data higher in the tree). For that, you might
look at the dclone
Thanks for all of your help! I got it with the module, but I am going to play with
some of that code now :). Thanks for all of your help.

What you mean by deep copy ?
Be more clear :-)

Deep copy.
I have a data structure (hashes of hashes)
I want to make a real/deep copy of the values to store elsewhere.
So when I change the values of one, the references don't
point to the same
values as the original data structure.
hence deep copy
