Generic wishful suggestion for courts, regarding any sort of computer-processed data which is a basis for legal action: Coin some fancy-sounding Latin phrase meaning "obvious computer failure", and make liberal use of that phrase in curtly dismissing legal actions (with prejudice) where some key piece of the assertion is clearly a product of "garbage in, garbage out". That might at least give some incentive to those…
> “null” is also a text string that in many programming languages signifies a value that is empty or undefined.
I can't think of a single language that does this. A null interpolated into a string or concatenated with an empty one could produce such a string. If that string value is then used to signify an empty/undefined value is misuse of the language.
