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.
