${(F)l} joins this huge array into a single string and then that
single argument is passed to "print".

print -l $l expands the array and passes all those words to "print",
requiring that they individually be copied at least one extra time.

Incidentally,
  print -aC1 $l
is even slower, but
  printf "%s\n" $l
is about the same as print -l.
