} From the man page, it sounds like ${^temp} or ${=temp} should
} work, but neither does.

${=temp} should have done it for you:

zagzig[562] x="foo -r bar -r baz"
zagzig[563] print -l ${=x}
foo
-r
bar
-r
baz

However, it would do the wrong thing if any of the original arguments
contained whitespace.

This is the right idea.  Unless you have shwordsplit set (which you must
not, or you wouldn't have needed ${=temp} in the first place) you don't
even need the quotes that Nemeth used; and unless you have shortloops
turned off you can just write it like this:

    local temp i
    for i; temp=($temp -r $i)
    command $temp
