That's not entirely fair. I was neck deep in SQL, and wanted to see if evaluation
could be adjusted to match the three-valued logic.
The advantages are considerable!
perhaps it's because of long exposure to c-style short circuiting logic; but i generally find the SQL NULL behaviour heavy and hard to tame. any non-trivial _expression_ quickly becomes a tangle of special cases to handle NULLs, and choosing the exact operator/cast function is a nightmare.
can you point some references that make it all "click" and see what i'm missing?
