--- Comment #1 from Adam D. Ruppe <destructionator at gmail.com> ---
I think this is undefined in the language.... at declaration level, there is no
real order of operations. So the static if and assign conceptually happen
simultaneously (this is why D doesn't need forward declarations).

Obviously the alias assign thing does not follow this rule. But then we need to
decide: does the rule change or does alias assign change? And i don't know yet.
