--- Comment #3 from johanengelen at weka.io ---
Thanks for explanation, of course, doh! :-)

The way I found out about this is that I did something similar to this:

```
// File weak.d
import ldc.attributes; //contains `weak` type

@weak void foo() {}
```

which then didn't apply `ldc.attributes.weak` to `foo`. The file name (-->
module name) "hijacked" the `weak` identifier...
I guess I should learn that the filename is part of the program.

Anyway, mark as resolved?
