I'm not sure what the original problem is, but just in case it's not
obvious, the code would fail (as Nicola notes below) because it would
raise an exception and crash as it iterates past the Object class -
NSLog() uses the -description method to log the class 'cl', but Object
does not respond ot that method. I don't know where Object would
appear in the iterated list (I'd have expected it to be right at one
end).

Perhaps we should add a category of Object in GNUstep-base, to implement
-description for it?

interesting idea :-)

technically we also need to add respondsToSelector:

I'm not sure what's best - maybe being able to remove Object and company
from libobjc would be the real solution :-)

I already added +description, -description and -respondsToSelector:

Removal of Object might be nice ... but we use Protocol, wo we would have to
replace it with a version which inherits from NSObject.
