Both unfunction and autoload -U will happily handle $@, so there's no
real need for the loop. You can redirect the unfunction 2> /dev/null
if you don't want to be informed that you specified a nonexisting
function as in the above.

You should also use - in case you ever want to specify a function
starting with - or +, eg unfunction - $@; autoload -U - $@ (another
non-equivalence in the code example above btw, -myfunc() autoload -X
will work as specified, but the second one will break for
-myfunc/+myfunc :)
