                 labels = [slabel for label
                           in self._file.readline()[1:].split(b',')
                           for slabel in [label.strip()]

         lines = [match.group(1, 2)
                  for raw_line in raw_lines
                  for match in [line_pat.search(raw_line.strip())]
                  if match]

But in all these cases I prefer the original loop.
