+Instead of using `java.util.List`, `java.util.HashMap`, and other standard Java collections, use `Seq`, `ObjectMap` and other equivalents from `arc.struct`.
 Why? Because that's what the rest of the codebase uses, and the standard collections have a lot of cruft and usability issues associated with them.  
 In the rare case that concurrency is required, you may use the standard Java classes for that purpose (e.g. `CopyOnWriteArrayList`).  
 
 What you'll usually need to change:
 - `HashSet` -> `ObjectSet`
 - `HashMap` -> `ObjectMap`
