Not a bug --- a Feature . . .
That is a legacy of Interface Builder on NextStep, from the days before the
IBOutlet marker was added.
If you care to try it out, you will find that a method declaration of this form:
- (void)doSomething: (did)sender;
is viewed by Interface Builder as an IBAction method to which you can connect
from some control . . .
That's also a legacy feature.
