- AppleLink gatewayed addresses are limited to 35 characters, and this letter
- has a longer return address. It has been mapped into the address above.
- Reply using that address, and everything should work. The actual address
- is in the Internet headers below.

- Isn't that supposed to happen in the TObject::initialize() method which
- almost nobody uses?
-
- Clearing the whole object handle in initialize() (minus the first two bytes
- of course) would probably take some time away, but on average, would that be
- more, or less, than the hassle every programmer goes through when SHe forgets
- to zero out a field? ;-)
- Or than the overhead of calling another chain of methods when creating a new
- object? (Use NewHandleClear?)
-
- How will MacApp 3.0 handle this?
