I could be wrong, but I think this is a bug.  The 
implementation of Set uses a List object internally and the
`count' method returns result of calling `count' on that
internal List.  The bug is that the Set_c class should
override the `getCount' method inherited from the
Collection_any class so that it too gets the count from the
internal List.  The "count" ivar in Set_c is superfluous.
(Did that make sense?  Sorry, that's probably more than you
wanted to know, eh?)

Anyway, the `count' method was replaced by `getCount' (ie
`count' is deprecated).  You *should* use `getCount' but in
this case...

If you got the time, it should be pretty easy to fix the bug
and submit a patch to Marcus or, preferably, address@hidden
If you don't, I'll probably have a chance to do that later
today.  (Of course, by now Marcus, if he's "online", has
probably got this all fixed... He's so damn quick sometimes!
I usually see his patch before I see the orginial post!)


Ken.
