} The point wasn't quite the same (didn't involve "source"-ing .zshenv). 
} $0 doesn't work if used inside startup files (.zshenv/.zshrc/.zprofile). 
} When you source it manually, it's not treated specially.
} 
} Just wanted to note that the '%x' that I pointed out does work, though:
} 
} ## as the first line of .zshenv (so, will be run when starting zsh)
} $ sed 1q ~/.zshenv
} echo in .zshenv 0=$0 %x=${(%):-%x}

And I just wanted to point out that ${(%):-%x} doesn't solve the problem
being discussed in the zsh-workers thread I referenced; in the workers
thread the desire is to find the name of the calling script, which has
not yet been assigned to $0 at the time .zshenv is read.

This led to the patch proposed here:

-- which has not yet been applied, the discussion having broken off at
this point:
