I think it's optional, it works with DMD 2.052

You use the mixin several times.

Hmm, I think I had a good reason. First it needs to be const so it works 
during compile time. But I think I used  a struct because I used that on 
another project which required more data than just then name the field. 
If I would store it in an array you could only do the mixin once, I 
think. And that would require you to use strings instead of aliases, I 

template foo (args...) {}

Does that work with aliases?

That field should absolutely be static, I'm currently working on fixing 
that. I didn't think of that when I implemented it. This will also only 
work with one mixin (see the answer for the third comment).
