I guess it's a personal preference (also for me), but I don't think there is a strict guideline on that. Interestingly enough, I think there is a piece of code in the styleguide that looks exactly like the code you had: https://llvm.org/docs/CodingStandards.html#turn-predicate-loops-into-predicate-functions

Some Clang subprojects tend to put braces everywhere though.

That being said, I guess no braces at all would be the best option here.
