I was looking at the code in the delete method of the Model object in Model.php. The code eventually calls a delete on the database but the return value from that call is ignored and it is assumed to be successful. There is even a comment to that effect in the code:

    // Once the model has been deleted, we will fire off the deleted event so that
    // the developers may hook into post-delete operations. We will then return
    // a boolean true as the delete is presumably successful on the database.

Why does the code ignore the return code from the delete? Why assume that the delete was successful?
