How do you think about to choose a more âimperative moodâ for your
change description?

I would prefer to specify the completed exception handling
(addition of two function calls) by a compound statement in
the shown if branch directly.

If you would insist to use a goto statement, I find an other label
more appropriate according to the Linux coding style.
