Using non-id sender in IBAction methods

Subject: Using non-id sender in IBAction methods

With the new dot notation I sometimes use explicit types in my IBAction methods:

- (IBAction)doSomething:(UIButton *)button ...

instead of

- (IBAction)doSomething:(id)sender ...

so I don't have to downcast "sender" to be able to use the dot notation.

Do others do this too? Is this discouraged for some reason?
