Any clue how I'd go about getting a Rack to use a non-ZClass as
the wrapper class for the returned objects? I'm looking at
_v_itemConstructor in Rack.py, and it looks like it requires a
zlass.  However, it is in a section that says "Optionally Overrideable",
but at this stage of my ZPatterns Zen I have no clue how to go
about override it.  Especially since I have *no* clue what the
black magic line using ComputedAttribute after the def of the
function does...

Actually I have a glimmer of a maybe-understanding, but it is making
my brain hurt to think about it <grin>.  If I'm right the answer
might be as simple as setting _v_itemConstructor equal to the class,
but I don't trust my maybe-understanding very far.
