Of course nothing can change the value of immediate Objects. :)

See my earlier posting about the lambda { } and Variable[:name] ways of 
doing this.

Ruby itself just treats variables as names for Objects. You can't really 
refer to a variable itself, you can only refer to the Object it is a 
name for. That's a surprisingly simple and non-confusing model. I think 
Ruby itself should not be changed. (Though it would be nice if it had 
something like Binding.of_caller built-in...)
