It's important that collections returned from `@cached` methods are not modified, otherwise future retrievals from the cache will return the modified collection. This applies to the return values from `@cached` methods and the values inside the dictionaries returned by `@cachedList` methods. It's not necessary for the dictionaries returned by `@cachedList` methods themselves to be read-only. Signed-off-by: Sean Quah <seanq@matrix.org> Co-authored-by: David Robertson <davidr@element.io>
