I understand your point, however, the lesser characters to parse, the better
readability is (usually). At least the proposed pattern is mainly used in
the kernel (you may grep for different patterns). It also has an educational
effect in case somebody takes this code as an example (for whatever reason).
With this we will show that *in practice* kernel prefers this style over
others.
