The @ looks like a handwritten 'a'. @in't gonna => ain't gonna => will
not. It's a bad joke, made as a way of saying that I also could not think
of a good mnemonic for '@' or ','.

It's a thing lounge entertainers said after they told a bad joke.

+1 ... if we end up displaying the not-true-and-not-evaluated 'z' state.

It does lend importance, but that's also the line continuation marker for
"comment". Would that be a problem?

+1, I was going to suggest '/' for a false state, with two possible
metaphors to justify it
1. the slash in a "no" sign ("no smoking", ghostbusters, etc)
2. the leading char of a c/java/javascript comment (what is written here
is just words, not code)
