I was hoping to figure out a better solution than a category on NSObject, but it's more tricky than I expected as explained in the code comment. See http://svn.gna.org/viewcvs/etoile?rev=7064&view=rev The thing I don't understand though is why the method body is not empty for - (uintptr_t)pointerSizedProxyNull { if ([collection isEmpty]) { return 0; } NSInvocation *inv = [NSInvocation invocationWithTarget: self selector: _cmd arguments: nil]; uintptr_t retValue = 0; [self forwardInvocation: inv]; [inv getReturnValue: &retValue]; return retValue; } Because when I run the test suite, this code is never executed.
