…ollection.unmodifiable{Set,Map}
[Double-brace initialization](https://stackoverflow.com/questions/1958636/what-is-double-brace-initialization-in-java) is commonly abused for its brevity, but has performance and clarity implications.
The use of `Collections.unmodifiableSet` and `unmodifiableMap` prevents outsider classes from modifying these collections, which is not desirable.
