The documentation for the `proxy' macro mentions lack of access in the
defined implementation to protected members:

,----[ proxy ]
| Note that while method fns can be provided to override protected
| methods, they have no other access to protected members, nor to super,
| as these capabilities cannot be proxied.
`----
 
I just tried to define a proxy that overrides a protected method in the
base class, and within that overridden method body attempts to call on
some other protected method. It fails, reporting

,----[ IllegalArgumentException message prefix ]
| No matching field found
`----

That confirms the warning in the documentation.

Is there any other way within Clojure to define a class that does have
access to the protected methods of its base class? My motivating
example: Writing an AbstractQueuedSynchronizer implementation, which
involves a lot of interplay among overridden protected methods and
calling on protected methods.
