This will not work. Future::then() returns another future which represents the
result of the execution of the attached continuation.
future<T1> f1 = ...
future<T2> f2 = f1.then([](future<T1> f) -> T2 { f.get(); return T2{}; } );
which allows to chain things:
future<T2> f3 = f2.then([](future<T2> f) -> T3 { f.get(); return T3{}; } );

This is just a variation to what I showed above.
