I think it is this...:

1) Closure mode:

There are two types of variables: TempVar and CapturedVar. TempVars  
are temporaries that are not referenced from blocks.
Thus in a case like this:

	| a |

	[a].

the a would be a captured var, as the block could live longer then  
the activiation of the method, it needs to be independed of it.
Instance variables are modeled as Captured Vars, too (receiverVar is  
then "self").

2) Non-Closure mode:

If I rememer correctly, in non-closre mode al temps are tempVars, and  
all instance variables are CapturedVars.
