Yeah, using the assignment's an extra line:

 >>> line_list = ['bar ']
 >>> item, = s
 >>> line_list.append(item)
 >>> ''.join(line_list)
'bar foo'

I still tend to write the extra line in cases like this -- it guarantees 
that the set is really the size that I think it is, where the 
iter(s).next() solution will not raise an exception if the set is 
actually larger.
