If a function handle of a class is used in its constructor, the class seems to
be broken afterwards. I attach a slightly contrived example that reproduces
the issue:

++
>> s = classbug ("gnu octave");
>> s = classbug ({"gnu octave"});
>> s = classbug ("gnu octave");
error: no indexing!
error: called from
    subsref at line 17 column 7
    classbug at line 10 column 18
--

As you can see, after executing the second statement (that makes use of a
function handle to the class), the first statement doesn't execute properly
any more, with subsref() being called inappropriately. It works if "cellfun
('classbug',...)" is used instead of "cellfun (@classbug,...)".
