    }
}


var x = new X([new Y], "test");

var source = Rx.Observable.of(x);
source.map(function(x_with_infered_type) {
    // type inference sort of works on this level
    return x_with_infered_type.; // i ctrl+space show "data, el, str" and others so not really ok
}).map(function(y_arr) {
    y_arr. // ctrl+space shows data, el, str
    // type inference is broken in intellij works in sublime
    //y_arr[0].
