I would suggest taking a look at the TryParse methods on the built in types like int. The return value is a bool to indicate success while the value is returned via an out parameter. This construct makes it useful to call this method in a looping construct where another return type would/might make it a bit more complicated.
On further reflection one con could be a tendency to just keep adding out parameters to a method instead of properly encapsulating the logic.
