This doesn't reproduce the environment Ray had because your positional parameters get substituted into their own words.

% cat /private/tmp/x.zsh
echo echoing1: $@
echo echoing2: $*
echo echoing3: $* $@ killed
echo echoing4: $@ $* dead
echo aaa^$*^bbb
echo ccc^$@^ddd
echo
echo "echoing5: $@"
echo "echoing6: $*"
echo "echoing7: $* $@ killed"
echo "echoing8: $@ $* dead"
% zsh !$
zsh /private/tmp/x.zsh
echoing1:
echoing2:
echoing3: killed
echoing4: dead
aaa^^bbb
ccc^^ddd

echoing5: 
echoing6: 
echoing7:   killed
echoing8:   dead
% zsh -P !$
zsh -P /private/tmp/x.zsh
echoing1:
echoing2:
echoing3: killed
echoing4: dead




echoing6:
