as well.

Thanks for the explanation. So what happens is that, thanks to 
`-b syntax`, semantic3 is not called on the functions which are 
outside the (dub) package. In other word, the following code:
```
--- foo.d
module foo;
import bar;
void main () @safe
{
     callSafe();
}
--- bar.d
module bar;
void callSafe() @safe
{
     notReally();
}
void notReally() @system {}
```

Will not error out (try it: `dmd -o- foo.d`). Which is the 
expected behavior in that case.

So all we need now is to have explicit `@system` on all 
functions, as Walter has proposed in the other thread.
