[Frama-c-discuss] Assign clauses with ghost variables

Hello,

In my humble opinion, there is lack of abstraction of Frama-C in such 
situations. You need to mention every modified variable in contracts, 
even those that you would like to be hidden. For example, I see no way 
to use static variables (variable local to a file, but if used should be 
mentioned in contract therefore seen from outside!).

Best regards,
