The ``++match++`` statement should be used only to clearly define some new branches in the control flow. As soon as a ``++case++`` clause contains too many statements this highly decreases the readability of the overall control flow statement. In such case, the content of the ``++case++`` clause should be extracted into a dedicated method.
