```d
import std.math;

std.math.string s = "hello";
```

Substitute `std.math` for any other module (including a completely empty
module). Substitute `string` for any other symbol in object.d.

As long as the module doesn't redefine that symbol, it's a pass-through for
object symbols.

Fully-qualified-names should only resolve to names defined within that module.
