<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Maybe a comment then? Generally, seeing a deref followed by an access is an anti-pattern, unless something has explicit knowledge about the refs that have to be held.</pre>

Minimal changes have been made as required based on real usage and getting a feel for it. As it is the core functionality is present. Resolvers can register, queries can be made (async / sync).
As the API was basically copy/pasted from the wiki page there still remain stubs to be filled in for higher level functionality (such as parsing and query sets).</pre>
