Is an enum not appropriate? Because it can be used to push

This is bad from an efficiency point of view. I think Don even
suggested to disallow it.

It still only existing way to define compile-time usable AA
value, disallowing it without fixing alternatives is not an
option.
There might be another way depending on how good the compiler is
at optimizing out pure functions.
Because in theory it'll only call it once (did test in this
context). But I don't know how it handles it within memory.
@property pure int[int] test() {
pragma(msg, "hit");
return [1 : 2, 3 : 4];
}
pragma(msg, test);
pragma(msg, test);
hit
[1:2, 3:4]
[1:2, 3:4]
