This is OT, buy..
Why you think that is a bad idea? Don't you need (sometimes) to distinguish
between one error and others? for example, don't you need to do or not to do
something depending on the error you received ? Ok, you can have the error
number as an instance variable and then use a switch or if but...I don't
know.
