If called without arguments it will produce a new Future from a new Promise which is implictly added to the dependency list.

Parameter futures

The list of futures we want to add to the list we depend upon.

Returns

Once the promise has been materialised (when either on_success(), on_failure() or get() has been called on this object), it is not possible to call depend() anymore.
