Wow, it seems that the automatic package is just the feature what I want!. will it damage or impact the type definition in package?

well... I mean if I define a type in an automatic package, will the type be deferent to non-automatic package? 


package automatic pkg1;

        t1 = 0,
        t2 = 1

        t1 = 0,
        t2 = 1
    } type_t;
endpackage
