I want to create a global immutable associative array and have

that?

With:
immutable int[int] aa = [1:2,3:4];

I get:
source/thing.d(1): Error: non-constant expression [1:2, 3:4]

And with:
immutable int[int] aa;

static this(){
        aa = [1:2,3:4];
}

int c = aa[3];

I get:
source/thing.d(7): Error: static variable aa cannot be read at 
compile time

Also associative arrays don't seem to have a .idup

Is there any other way to do this?

Is an enum not appropriate? Because it can be used to push 
constants and available at ctfe.

enum int[int] aa = [1: 2, 3: 4];
pragma(msg, aa);
