On data types

[Ursula Dreier]

There is a way to simulate a pointer to a class aX: Create a new class
aPX containing just an instance item of class aX. Because the copy is a
flat one, you can have instances reference the same aX object.

But note also: The instance item is guaranteed always to reference some
aX.

BTW: If you wrote
 MailAddress = Template.MailAddress
that would just copy a reference, so that this.Mailaddress and
Templat.Mailaddress would actually refer to the same object.
