Heh, it wasn't obvious that list(xxx) copies data either (I thought of
it as being like a typecast), but I just checked, and it does copy.
I'll have to remember to do it like that.  I do like it better than
xxx[:] which is what I'd been using because I remember seeing that the
copy module does it that way.
