@in't gonna execute it?
Hmmm... This is too much of an Americanism, IMHO.
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 ','.
I'm here all week, try the veal.
Sorry, syntax error, you have lost me. Some googling suggests a reference to post WW2 "lounge entertainers", probably in the USA. I also do not understand why this would mean "yes".
It's a thing lounge entertainers said after they told a bad joke.
. for z (waiting for the end of the sentence, i.e. endif)
+1 ... if we end up displaying the not-true-and-not-evaluated 'z' state.
& for t (no real mnemonic)
For two states:
* for being executed (beware, it is ***important***)
It does lend importance, but that's also the line continuation marker for "comment". Would that be a problem?
/ for not (under the hood, and it is opposed to *)
+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)
