Strange warnings when unloading packages with S4 classes
...h true:
* The package has an S4 class which inherits from a class outside of the
package.
* The NAMESPACE file contains import(methods)
I've created some very simple test packages here which illustrate the
problem, along with instructions on how to duplicate the warning.

The warnings only appear when unloading the package where both of the
conditions above are true. I'm not sure why import(methods) should make a
difference, but it does.
Is this a bug in the implementation of S4?
Best,
