package reflection

[sigod via Digitalmars-d-learn]

In the video "Case Studies In Simplifying Code With Compile-Time 
Reflection" [was pointed out][0] that it is possible to reflect 
on imported packages.

So, I tried:

reflection.d:
```
import std.stdio;

import test.module1;
import test.module2;

void main() {
	foreach (m; __traits(allMembers, mixin(__MODULE__))) {
		writeln(m);
	}

	writeln("--------------");

	foreach (m; __traits(allMembers, test)) {
		writeln(m);
	}
}
```

test/module1.d:
```
module test.module1;

void module_1() {}
```

test/module2.d:
```
module test.module2;

void module_2() {}
```

It produces:
```
$ rdmd reflection.d
object
std
test
main
--------------
object
module_1
```

As you see `module_2` wasn't listed. If I change order of import 
declarations `module_2` will be listed instead of `module_1`.

I also tried to create `test/package.d` and publicly import other 
modules through it, but it behave in the same way.

So, how to reflect on imported packages?
