Well...
The documentation for removeObject: says "Removes all occurrences of
anObject in the receiver", so yeah, I'd expect that behavior :)

Greetings,
I just discovered something interesting behavior-wise in
NSMutableArray... Since the class does not handle duplicates, you can
add the same object several times to an array and it will appear in
several slots. But if you then call removeObject: on that same object,
ALL INSTANCES of the object are removed from the array! I wrote a
short test app to confirm that I wasn't dreaming this up.
Is this normal, expected behavior? Shouldn't the class stick to never
handling duplicates no matter the method call?
(And yes, I know about NSSet and NSCountedSet... That's not the issue
here :)
