Thanks a lot!

I don't think you can initialize them this way.

See http://www.digitalmars.com/d/arrays.html#associative.

P.S. You should better ask such questions in digitalMars.D.learn newsgroup.

D does not yet support compile-time initialization of associative arrays=
.  =

Such arrays need to be initialized at run time, most usually in the modu=
le  =

constructor ...

--- sample -----------
import std.stdio;
const int red =3D 45;
const int orange =3D 71;
const int yellow =3D 13;
const int blue =3D 92;
const int green =3D 88;

const int [char[]] arr;

static this()
{
     arr["apple"] =3D red;
     arr["orange"] =3D orange;
     arr["banana"] =3D yellow;
     arr["berry"] =3D blue;
}

void main()
{
     foreach(char[] k, int c; arr)
         writefln("%s is %s", k, c);

}
--------------------

Note that you can still have a 'const' associative array even though it =
is  =

initialized at run time because such an array can *only* be initialized =
in  =

the module constructor.
