What's more, even if you do find what looks like a copy constructor, you've
not actually got any guarantees that it really is a copy constructor. For
example:
public class TreeNode {
public TreeNode(TreeNode parent) { ... }
...
}
If you were using reflection to look for copy constructors, t

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:
1. Get type of anyObj
2. Find copy constructor for that
Is there a good design reason to favor implementing ICloneable rather than
implementing a copy constructor?
