[Gambas-user] An other OO problem.

[Jussi Lahtinen]

If I have understand concept correctly, I think this;
http://gambasdoc.org/help/comp/gb/object%5B%5D/copy
is little misleading.
"Returns a deep copy of the array."
Objects copied with this method doesn't seem to be deep copied
(shallow copy instead).
