Static arrays really don't get any love :(

I also recently filed a bug:
https://issues.dlang.org/show_bug.cgi?id=22198

I think you should also file these ones.
If they're wrong, it'll just get ```RESOLVED INVALID```. Even 
better, someone here can tell why the above mentioned behaviours 
aren't bugs and you can just do it yourself.
