What additional indirections would deriving from a base class introduce?
depends on the inheritance type - private inheritance from helper == 'implemented-n-terms-of': functions of helper are not part of the public interface (future/promise has to invoke helper functions internally) - public inheritance from helper == 'is-a': functions of helper are part of the public interface, but I don't like to track a future as the same as a promise (or packaged_task) => void foo( helper &) could be called for future and promise so I believe using template specializationonly is reasonable
