I agree on principle, but I think this one warrants for an exception. This 
method is really meant to be called from a signal, and putting such a type in 
the signal's signature would be very cumbersome (and using 'alien' types in 
signal/slots is discouraged).

So no matter how you turn it, you will see and use this method with a bool arg 
at the application level.
