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.

    Cheers,
