 The query system allows for applying [modifiers][mod] to queries.
 These modifiers affect certain aspects of how the system treats the query with

- - `anon` - This attribute makes the system use "anonymous" dep-nodes for the given query.
-   An anonymous dep-node is not identified by the corresponding query key.
