Because you want to have a portable proxy?

Hi!
I have a near-to-be naive question. Maybe there is something obvious, but I
cannot see it. Consider the following implementation of a proxy:
-=-=-=-=-=-=-=-=-=-=-=-=
Object subclass: #MyProxy
instanceVariableNames: 'object'.
MyProxy >> object: anObject
object := anObject
MyProxy >> doesNotUnderstand: aMessage
^ object perform: aMessage selector withArguments: aMessage arguments
Object >> wrap
self becomeForward: (MyProxy new object: self; yourself)
-=-=-=-=-=-=-=-=-=-=-=-=
The problem is with wrap. After the becomeForward:, MyProxy has itself in the
object variable. Even self is apparently subject to the #become.
It means that the following code loop indefinitely
-=-=-=-=-=-=-=-=-=-=-=-=
d := Dictionary new.
d wrap.
d add: #foo -> 10
-=-=-=-=-=-=-=-=-=-=-=-=
I know there is Mariano’s library to write proxy. But I still wondering whether
this could be done simply.
Any idea how to simply create a proxy?
Cheers,
Alexandre
