+ *
+ * If something isn't addressed in either of those, some other common community rules are
+ * used that might not be addressed explicitly in PSR-2 in order to improve code quality
+ * (so that devs don't need to comment on them in Code Reviews).
+ *
+ * For instance: removing trailing white space, removing extra line breaks where
+ * they're not needed (back to back, beginning or end of function/class, etc.),
+ * adding trailing commas in the last line of an array, etc.
