In fact, the cdr suite (chpwd_recent_filehandler) does this as essentially
print -rl -- ${(qqqq)array_of_dirs}
The four q's means use $' style quoting for this. The advantage here is
if a string contains a newline (bad karma for a directory, but let's
think in general) it gets written as $'...\n...' --- so it's always safe
to read back a single line at a time and strip the quotes with ${(Q)...}.
For efficiency, in fact, it reads the file into an array of lines using
${(f)"$(<$file)"} and takes the lines out of that array.
