-We write a user-controlled value into the object ``b`` at the access path ``[a, x]``. Afterwards, ``b`` is passed to ``use_data`` which we assume we don't have the definition of in the database. We now want to track this user-input flowing into ``use_data``.

-The dataflow library actually has a specific tool to handle this scenario, and thus we don't need to add any additional flow steps using ``isAdditionalFlowStep`` to handle this. Instead, we have to tell the dataflow library that ``use_data`` may implicitly read the data from the object that it has been passed. To do that, we implement ``allowImplicitRead`` in our dataflow module:
