Currently in D if you define an array with enum index you get
an associative array, that is wasteful in both memory and
performance for most enums that have contiguous values (but I
think maybe D implementations will be free to use a more
efficient array here, because the interface of AAs is opaque).
And there is this small problem too:

Kagamin:
I was surprised a little when compiler rejected `ref in`.
But this compiles:
alias int[1_000] TA;
void foo(const ref TA a) {}
void main() {}
