I don't see anything in the docs about a package import. Public, Private, 
Static, but not Package.

Here goes my opinion about this again: any modifier that doesn't make 
sense in a given context, should be a compiler error. This thread is and 
example of what happens if this is not the case.

"static" does not make variables private as in C.  "private" does that. 
Declarations are implicitly public, hence why you can access it in main.

 module package1.module2;

 module package1.module3;
 package import package1.module1, package1.module2;

Yeah, what the hell is "package import"?

 module main;
 import package1.module3;

 void main(){
  variable1 = 5;  // Why variable is accessable?
 }

yes  static int variable = 3; actually means
public static int variable =3;
if you write
private static int variable =3;
you can't access it from any other module
if you write
package static int variable =3;
you can access it from module2 and module3 (that are in the same 
package) but not from main.

 
 module package1.module2;
 
 module package1.module3;
 package import package1.module1, package1.module2;

 
 Yeah, what the hell is "package import"?

this is most likely not implemented, it is documented nowhere, you 
might expect it for symmetry reasons, but it is not there.
If you think it should be there (and really I cannot think a good case 
in which you need it) try filing a bug report...

I agree in general, but recently someone in the main D newsgroup has explained
me why the 'scope' attribute can't work in the way you like, so some leeway may
be inevitable (but I presume less than the current one).
