Does my style of code have any point in this subject? (Although this is a test, and as I figure out readability, it's much more important. I know one way Arrow tackles this is to define ARROW_PREDICATE_TRUE and ARROW_PREDICATE_FALSE, which becomes handy in error-checking code.) -- This is an automated message from the Apache Git Service.
