That may appear to work, but I would *strongly* recommend against it,
because what happens when you use enum with an AA, is that the AA will
be created *at runtime*, *every single time* it is referenced. (It is
as if you copy-n-pasted the entire AA into the code each time you
reference the enum.) Which will introduce ridiculous amounts of
redundant work at runtime and cause a big performance penalty.
You can use an enum to declare the AA and then assign it to an immutable variable using "static this". The you would only use to the immutable variable and never the enum.
enum aa = [1 : 2];
immutable int[int] iaa;
static this()
{
iaa = aa;
}
