 Cute, but unfortunately it conflicts with established
 usage of the word 'nor', which would suggest that
 a nor b == not (a or b).

Agreed. If this is going to be a keyword rather than a symbol, it really has to read like English, or at least like abbreviated English, with the right meaning--something like "foo, falling back to 'foo was None' if needed".  Something that reads like English with a completely different meaning is a bad idea.
