Also, while classes work to some extent in CTFE, they can't be assigned to 
anything which will persist beyond compile time. Similarly AAs can't be kept 
around after compile time, and I don't know if they work at compile time at 
all. I don't believe that unions work in CTFE either, though they're not 
mentioned in that section for some reason.
