I think 

-- the example is a nice one for human readers
-- it is a useful test on the codebase (at least one version I created
   of example failed it).

My problem is with

Now if we could keep running, we would get to see _all_ the problems
and be able to ignore those we knew about. 

Alternatively, I could fix the specific case, and make this a warning and
do-nothing condition.  I am inclined to do that anyway. The only
knock-on effect I can see is that some examples call other examples, and if
the included ones are missing then the main example main fail in an
unanticipated way.
