# If an error is raised while loading the module,
# and it isn't handled (or it is re-raised), it
# will go straight to the WSGI server.
# ==================================================
model = Model()

    model.load()
except Exception as ex:
    # Handle the error here - log and re-raise to the
    # WSGI server, retry, or whatever...

api.add_route('/foo', resource)

# ==================================================
# At this point the module has been parsed and
# loaded by the WSGI server. Future errors raised
# inside your app will go through Falcon's error
# handling logic.
