I only see 3 calls in OE core, two of them uses None as first argument, 
and the last one uses a list, also if you check the function it will 
handle the argument as a list; so the function expect a list or None. 
And the list support the copy method, I just double check it:

 >>> l = [1,2,3]
 >>> l.copy()
[1, 2, 3]
