While I was looking at zmv:

I read:

if [[ -z $action ]]; then
  # We can't necessarily get the name of the function directly, because
  # of no_function_argzero stupidity.
  tmpf=${TMPPREFIX}zmv$$
  print -P %N >$tmpf
  myname=$(<$tmpf)
  rm -f $tmpf

  action=$myname[-2,-1]

  if [[ $action != (cp|mv|ln) ]]; then
    print "Action $action not recognised: must be cp, mv or ln." >&2
    return 1
  fi
fi

We could use:

action=${(%):-%N}
(which looks like a very complicated smiley)

Also, for tempfiles, there's

tmpf==(print -P %N)

Also, I read:

print -P "%N: unrecognized option: -$OPTARG" >&2

If $OPTARG is "%", that fails 

Maybe it would make sense to have a %P as a printf format for
prompt expansions:

printf '%P: unrecognized option: -%s\n' %N "$OPTARG"

Of course, the above can be written:

print -nP %N >&2
print -r ": unrecognized option: -$OPTARG" >&2

or

print -r "${(%):-%N}: unrecognized option: -$OPTARG" >&2

though

Also, I've seen some problems with the: $find variable:

$ zmv -wn '[a\\]' '$f'
zmv: warning: no wildcards were found in search pattern
$ zmv -wn 'a#' '$f'
zmv: warning: no wildcards were found in search pattern

Please find a patch attached.

Please test as I'm not really confident that I didn't introduce
a few pairs of half-dozens bugs ;)
