Thanks for your quick feedback.

I would prefer the approach above so that an extra goto statement could also be avoided before.

Do any more contributors insist on such a code layout?

I am just curious on how we can achieve progress here.

This is generally fine.

I asked also because other well-known contributors showed strong reactions for this change pattern (with the help of a script for the semantic patch language). Would you care for similar updates in source files like the following?
