Not a bug ...
This is correct behavior as a string is not a number so isEqual: should always
return NO for a comparison of the two.
In general, objects of different classes are not equal ... unless both are instances
of private subclasses in a class cluster.
OPENSTEP and MacOS-X behave the same way.
