 /**
  * An ArrayCollection is a Collection implementation that wraps a regular PHP array.
  *
+ * Warning: Using (un-)serialize() on a collection is not a supported use-case
+ * and may break when we change the internals in the future. If you need to
+ * serialize a collection use {@link toArray()} and reconstruct the collection
+ * manually.
