Not very practical but fun to make and good for wtf moments when
reading old code :)
self.attrs['class'] = ' '.join([x for x in self.attr.get('class') and
self.attr['class'].split(' ') or []] + [self.pastClass])
Could make it a little shorter with two lines:
e, a, p = self.attrs.get('class'), self.attrs, self.pastClass
a['class'] = ' '.join([x for x in e and e.split(' ') or []] + [p])
Could fit the final version in with three tabs and it's only 79 chars!
