Hi guys,
I'm updated from DMD 2.060 to 2.061 and I just run into some 
trouble by using associative arrays. Let's say I've the 
following few lines:

string[string] myValues;

ref string getValue(string v) {
   return myValues[v];
}

void main() {
   getValue("myValue") = "myString";
}

I get a range violation in getValue() because the entry does 
not exist. But as far as I know, this worked in 2.060 (no range 
violation). One idea was to initialize the value in getValue() 
if it does not exist, but my associative array looks like:

string[string][][string] myValues;

... how to initialize this? So, is this a bug or is it my 
mistake?

Did that really work before? Looks like a bug as you are 
accessing an element that doesn't exist.

The following works:

import std.stdio;
void main() {
    string[string][][string] myValues;
    assert(myValues.length == 0);

    myValues["a"] = new string[string][100]; // Doesn't have to 
create 100 elements of course
    assert(myValues["a"].length == 100);
    assert(myValues["a"][0].length == 0);

    myValues["a"][0]["b"] = "aoeu";
    assert(myValues["a"][0]["b"] == "aoeu");
}
