remove list member during a forEach: traversal?

[Rick Riolo]

Suppose I have a List alist, and suppose I want to
send messages to all its members:

   [alist forEach: M(myMsg)];

My question is: can myMsg remove from alist a list member 
to which it was sent (and still have the forEach carry on 
to process the rest of the items in alist)?
I was thinking myMsg could have access to alist,
and perhaps it could include

   [alist remove: self];

Will this work?
thanks!
