I keep getting a

Note, I think you need at least Sound.SOUND_EFFECT, etc.

This bug looks particularly relevant: https://issues.dlang.org/show_bug.cgi?id=11221

I think it should really work.

The C-style struct initialization in there is a problem. Try making it

immutable Sound[string] soundLibrary  =   // line 148
[
    "SCRATCH"          : Sound("scratch.wav", SoundType.SOUND_EFFECT, null ),
    "BACKGROUND_TRACK" : Sound("beat.wav",    SoundType.MUSIC,    null ),
    "HIGH"             : Sound("high.wav",    SoundType.SOUND_EFFECT, null
    )
];

using positional values instead of named. Moreover, note that such initialization needs to be done in a function, not at global scope. you may need to declare it outside then initialize it in a static constructor.

It's not just in associative arrays it doesn't work. It basically only works in variables declarations:

Right, but it doesn't work in variable declarations if that variable is part of an associative array.

In other words:

struct S
{
   int x;
}

struct T
{
   S s;
}

T t = {s: {x: 1}}; // nesting works here
S[] arr = [{x: 1}, {x:2}]; // and here
S[string] aa = ["first": {x: 1}, "second": {x: 2}]; // but not here???

Aha, I see. Didn't expect any of those to work.
