It's from Bernoulli.

Huh. And here I was thinking the obvious thing is that it's a way to have "null" without it accidentally being parsed as null.

Interesting. Is that a unit he invented or is it just a reference to his last name that stuck?

From Bernoulli maps apparently. I still don't understand why[0].

		A bit of a garden path path sentence... I believe "maps" in "maps to" was being used as a verb. So "noul"--short for Bernoulli as in the Bernoulli distribution--"maps to if-statements."
