Why?  That appears to be pointless code style thrashing.

Converting code with a single return into code with multiple returns.
Which arguably makes it harder to prove properties about.

Further if you want to use the style you suggest a label name like err
is better than the name out.

But in this case where we have multiple results I don't like the proposed
change in style at all.  Especially with no rational.
