I get a runtime error:

Uncaught Invariant Violation: Could not find "store" in the context of "Connect(MyView)". Either wrap the root component in a <Provider>, or pass a custom React context provider to <Provider> and the corresponding React context consumer to Connect(MyView) in connect options.

For:

ReactDOM.render(jsx('
    <Provider store=${store}>
        <MyView />
    </Provider>
 '), Browser.document.getElementById('app'));

And I'm not sure why... haxelib:/react-next#1.116.0
