Don’t be an idiot. Things will fail. In the absense of Design by Contract or somesuch, errors will happen. Throw them. Catch them. But at least throw them, instead of letting your code die six hundred lines later with a “Cannot cast null value to string” when you finally get around to trying to print something out.
