Can I use "static if" or "static this()", or "mixin" or some 
other technique?

Yeah, just declare the array outside, then initialize it inside 
a static this() constructor.

int[int] foo;
static this() {
  foo = [1:1];
}


I hate to keep being a bother, but my project with the below 
static this() now compiles fine, but aborts during runtime with a 
"a problem caused the program to stop working ..."

Does static if have some pitfalls I'm unaware of?

static this()
{
    tracks["SCRATCH"] = Track("scratch.wav", Sound.SOUND_EFFECT, 
ONCE,    null );

    // or this form code segment

    Track[string] tracks =
    [
        "SCRATCH" : Track("scratch.wav", Sound.SOUND_EFFECT, 
ONCE,    null )
    ];

}

I even tried just foo = [1:1]; but that crashed during run time.

I have a writeln() statement just after main() so I know it is 
occurring before main().
