Note though that the copy function as it was given by the original poster
is doing nothing more than a single level copy, rather than a deep copy.
So if you have an array of arrays, making a copy will indeed yield a new
array, but it will still contain references to the original deeper arrays,
and so those could be modified.

Most DGD mudlibs I've seen have fixed that adequately with pretty trivial
code.
