See also the bash-style ${array/#/prefix} (well you'd also need
a [@] in bash):

print -r -- ${(j[, ]list/#/DNS:}

(also remember "print" like "echo" doesn't do what you want by
default, you need -r with print and -E with echo, misdesigns
inherited from ksh/PWB. And -- or - to mark the end of options).
