Ah, I get it.  The new string library allows both string
and unicode list elements and seperator; returning string
only if both terms are string.

My concern about performance disappears because I can get
the join method of the seperator, as in this hypothetical
example:

  join = "\t".join
  for i in range(data.shape[0]):
    print join(data[i])

Thanks!
