Reduced further:

----
class MyStore
{
    class SingleStore
    {
        static void New() // Removing 'static' compiles
        {
            new SingleStore();
        }
    }
}
----

And now the problem can be spotted:

SingleStore is a nested class. That means, instances of it are bound to 
MyStore instances. But New is static, so it doesn't have a MyStore to which 
it could attach the `new SingleStore`.

That error message is pretty awful. I filed an issue:
https://issues.dlang.org/show_bug.cgi?id=15049

As for a fix: I guess SingleStore isn't supposed to be a nested class. Mark 
it static then.
