Hi,
I do not understand why struct initializer works for arrays but

associative arrays:

struct Bar
{
    string s;
}

struct Foo
{
    Bar[string] asso;
    Bar[] arr;
}

void main()
{
    Foo foo = {
        arr: [{s: "123"}],
        asso: ["0": {s: "123"}] // does not work
    };
}

The coding for both types of arrays looks very similiar:

I cannot spot the difference.

Kind regards
André

This might just be a bug. Changing the initializer to an explicit 
call to Bar constructor compiles just fine

Even just doing

    Foo foo = {
        arr: [{s: "123"}],
        asso: ["0": {"123"}] // does not work
    };
