itself to perform the add but doesn't seem to be as straight forward
as initially thought without writing lots of code to check for which

it to the actual Collection.

One way would be to make the Key argument mandatory or use a default,
making the Before and After arguments irrelevant. My collection classes
are always for object's, rather than values, so this is easy for me: I
either default to the object's Name property or use its ObjPtr() value
as appropriate. This makes the Remove method very easy i.e. use the Key
to remove the object. That said, I rarely use the remove method: easier
to start over using a new collection class instance.
