Actually, given the definitions there, what Gambas is doing is a deep copy.

In a shallow copy, there's only one object (array, in this case) when the 
copy is complete, and two references to it (and the originally declared 
second array's allocated memory is lost to either garbage collection or a 
memory leak), but in a deep copy, there are two independent copies of the 
array when you're done.  In Gambas the latter is true.
