I don't; I advocate doing

   puts ary

and let Ruby do the work :-)  I know, I know... it's not as explicit
in its handling of each element.  But once someone tells you how it
works, you know; and I think learning that is one of the Ruby rites of
passage (like learning that #{...} interpolates more than variables
:-)
