private module symbols

[Flo]

Hi,

Im kinda confused about the protection attributes on module level.
The case:
I've got 2 modules.
test1.d

module test1;

import test2;

int main(char[][] args)
{
        Test2Struct s;
        return 0;
}

and test2.d

module test2;

private struct Test2Struct
{
        int var;
}


>From my understanding of the docs, i shouldn't be able to use the struct in 
>test1. But it compiles and runs fine and so i'm not sure how to hide symbols 
>to other modules. Is it possible at all?

(oh and im using dmd 1.043)
