Revision 380

added: two flags to FunInfo<> struct:
       // indicates that this function is from [for ...] statement
       bool is_for;

       // indicates that this function is from [for ...] statement
       // and this is a first iteration (iter=0 too)
       // this is only for convenience -- you don't have to check is_for and iter==0
       bool is_for_first_iter;
