I did leave one instance of += in the exercise in episode 18, since its point was to emphasize the value of readable rather than terse code and I feel that running into unfamiliar syntax in the wild is a pretty common experience with codebases that need refactoring. Happy to remove it for overall consistency, though.
Resolves #582 per issue discussion.
