hey, speaking of clone, how could I clone an instance of an XMLReader
object?
When I load an XMLDocument object using an XMLReader object, the reader is
at the end of the document, but I still need to use it... is there any way
to do this without loading 2 separate XMLReader objects?
e.g.
Dim xmlR A New XMLReader = goGetmyReader()
Dim xml As New XMLDocument
xml.Load(xmlR)
' now loop through reader
While xmlR.Read()
' oops this will never execute
' so I need a copy of xmlR before loading it into the XMLDocument
above.
....

I don't know what you'd call a good reason, but here's one that's good
enough for me - it's easier to call IClonable.Clone() than it is to call a
constructor for an unknown type.
Compare:
object clone = ((IClonable) anyObj).Clone();
To:
<pseudocode>
1. Get type of anyObj
2. Find copy constructor for that type
3. Invoke copy constructor
</pseudocode>
It's also easier to tell if it's supported by an object.
Cheers,
G.

Is there a good design reason to favor implementing ICloneable rather than
implementing a copy constructor?
