} No, it is *not* executed on the first call. Ok, it is executed, but
} one won't see that because it only redefines itself (and any helper
} functions).

I think you're wrong, but it's because I've tricked you with a typo.

The usual idiom is `[[ -o kshautoload ]] || $0 "$@"', but I wrote `&&'.

With && zsh will execute the function, because kshautoload does *not*
become temporarily unset just because the function is loaded with zsh
semantics.  However, the first execution just harmlessly redefines the
function, so you won't notice.
