join() is special indeed, but what about the semantics we talked
about last year (?)...

join(seq, sep) := seq[0] + sep + seq[1] + sep + ... + seq[n]

This should fit all uses of join() (accept maybe os.path.join).

How about naming the beast concat() with sep defaulting to '' to
avoid the problems with os.path.join() ?!
