I remember this insight from a paper on SQL's 3VL issues (true/false/null), and I think it somewhat apllies to nulls issues inanguages; its a 3VL logic system that doesn't go all the way. Sometimes it gets forced into 2VL semantics (conditionals), and the conversion is where all the problems lie. If it stayed true to its word, and fully embraced 3VL, there wouldn't be an issue.
