Re: How Can an Object Read its Own Name

[Brian Casiello]

I'm a Smalltalk newbie, but I'll give this a shot, and hopefully learn 
something!

Consider

    Foo := Bar new .
    Sna := Foo .

Foo and Sna are two different names for the exact same object. Which one 
is its unique name?

How to handle would depend on exactly what you're trying to accomplish. 
One possibility is to give the object a unique name when it is 
constructed using an instance variable. You'd do something like

    Foo := Bar newWithUniqueName: 'Kilroy' .

The name would carry along with the object, no matter what variable(s) 
it happens to be assigned to. It could even be part of a collection, not 
assigned to a single named variable at all, but the object would still 
know its own name.

If that doesn't meet your requirements, you really need to know the name 
of the (a) variable that the object is assigned to, I'm afraid that's 
beyond me.

HTH,
Brian
