} So, you could do something like this (using the (b::) subscript flag as
} well):

} local haystack="$1"

} (( idx <= $#haystack ))

This example might be a little clearer if we show the index where the
match was found and use a match pattern longer than one character:
% () {
local haystack=$1 needle=$2
integer idx
while idx=${haystack[(ib:idx+1:)$needle]}
(( idx <= $#haystack ))
do
print -r - $idx $haystack[idx,idx+$#needle-1]
done
} foobar 'o??'
2 oob
3 oba

(I also removed all redundant quotes and braces, since the original
would only work in native zsh emulation anyway.)
