It's blocking my code from porting to D2.0. So I mark this at a little higher priority .

When did this ever compile? I think this is an unimplemented feature, not a regression.

Uh, are you talking about AA literals?  They've been in D since 1.014 (April 26).. this code works with D1.

It won't compile at global scope, and never has.

http://www.digitalmars.com/d/1.0/expression.html#AssocArrayLiteral

"An AssocArrayLiteral cannot be used to statically initialize anything."

Then it's not a bug in any way, is it?  It's stupid, but according to spec. And it's not a regression because nothing changed.  It works fine in 2.008 too.

I don't have a 2.0 installation handy so I don't know, but yes: if it works fine when doing the initialization in a static constructor, for instance, then it's not a bug.

Oh, you remind me that the severity is regression.

It compiles by D1.X compilers.

And spec gives a simplest example with same length string literals
If I remember correctly:
int[char[]] aa=["aa":1,"bb":2,"cc":3];

------- Comment #4 from matti.niemenmaa+dbugzilla@iki.fi  2007-12-13 04:40 -------
It has never compiled, neither in 1.0 nor in 2.0.

http://www.digitalmars.com/d/expression.html#AssocArrayLiteral gives the example "[21u:"he",38:"ho",2:"hi"];" but doesn't assign it to anything. It also says "[a]n AssocArrayLiteral cannot be used to statically initialize anything."

This means that code of the form "<associative array type> foo = <associative array literal>" doesn't work, nor has it ever.

Unless code like the following fails, this is an invalid bug:

int[char[]] a;

static this() {
        a = ["aa":1,"bb":2,"cc":3];
}

The following code compiles on both GDC and DMD, but DMD compiled code throws an array bounds exception when executed. I think DMD might have a bug.

test.d
------
import std.stdio;

void main() {
        int[char[]] aa =  ["aa":1, "bb":2, "cc":3]; // Fails
        //int[char[]] aa; aa =  ["aa":1, "bb":2, "cc":3]; // Fails
        //int[char[]] aa; aa["aa"] = 1; aa["bb"] = 2; aa["cc"] = 3; // OK
        assert(aa.length == 3);
        assert(aa["aa"]==1); // Fails on DMD 2.008. Error: ArrayBoundsError
test(8)
        assert(aa["bb"]==2);
        assert(aa["cc"]==3);
        writefln(aa["aa"],aa["bb"],aa["cc"]); // On GDC outputs: 123
}
