I think Walter said something a while back to the effect that making it
possible to statically initialise AAs isn't feasible because it requires
setting up a complex structure on the heap. The best you could do would
be to *pretend* to statically initialise them, and actually really
initialise them in a module ctor.
Which is exactly what you currently have to do.
Could be wrong; that's just what I remember from the last time this came up.
