Expected behavior.

You'll need a copy() function which takes an array and returns
a copy of it. Melville has one, although it doesn't handle
recursive arrays (arrays with elements that are arrays)
though it could be reasonably easily extended to do that
(and one day it will). I'm sure the kernel lib has one
too, not that I could tell you where. Take a look at the
sources and see how it's done.
