Hello,

One of the questions with having meta objects for variables (Slots and Globals) is: For what is is good?

Here is one example� in early stage but working.

    

Now working: MetaLinks on Class Variables. 

|link |
link :=  MetaLink new 
    metaObject:  Halt;
    selector: #now.

(TT classVariableNamed: #T) link: link.

� and any access of the class var will trigger a Halt.

next: Globals, this means

	Object binding link: link

should trigger the link whenever the global Object is read anywhere�
