I'd argue towards not using grouping within declarations (except within  
with or add statements). Then this problem is taken away and it would  
increase readability.

If you insist on allowing grouping for decalarations I'd argue for using  
";".

The main problem is that "default" does not need a value but may be used  
as modifier in assignments and definitions. For such modifiers ("local" is  
another example for such a modifier), the AUG is contradictory (see  
section 8.13).
Therefore one has to guess what the AUG actually means.

I'd consider using AUG's example for the use of the modifier "local" with  
a sequence of assignments (AUG section 8.13 bottom of page 108) a good  
guess.
Therefore, I'd go for ";".

Kind regards,
Christian
