That's a very unequivocal rule-of-thumb then :-). For me, zsh's word-splitting rule is one
of its best features, and I think anyone who turns it off deserves all their pain! Agree
quoting $@ makes sense here since this is a wrapper, but I find more often dropping empty
arguments is often very helpful after splits and suchlike.
But as to "${opts[@]}"... Just too ugly to do that all the time, no? Instead, use
zsh's awesome sticky emulation:
emulate zsh -c 'autoload -Uz ~/my-zsh-funcs/*'
Very helpful for insulating the risks of unexpected option settings, and makes it
safe to use unquoted variables. As a rule of thumb, at least :-)
