Is there any reason why the following fails with an ArrayBoundsError error?

     import std.cstream;

     void main ()
     {
          string [string] array = ["name": "value"];
          dout.writefln ("value: %s", array ["name"]);
     }

I've been using the following work around, But I'm not sure why the above fails.

     ...
     string [string] array;
     array ["name"] = "value";
     ...

Can anyone explain this?

You can't do that (as of now).

Might be helpful to know what version of the compiler you're using. This code works for me in 1.034.

It doesn't for me (2.019)

It is a bug in D2. http://d.puremagic.com/issues/show_bug.cgi?id=2333 Gide
