==> Error: non-constant expression `["foo":5L, "bar":10L, "baz":2000L]`

Also: I don't understand the error message:
* What is non-constant in the *expression*?
* And why should it be constant at all?
(Removing "immutable" does not help...)

If I'm right, you can't use this syntax with global array. Insted this works: void main() { immutable long[string] aa = [ "foo": 5, "bar": 10, "baz": 2000 ]; } You should init global AAs using static this() { } as explained in the same doc Andrea

Well, bug in implementation. That is *supposed* to work, but the compiler never implemented it. The docs really should point out this fact explicitly, though.

Especially since it's hard to workaround inside function scope.
