I would generally be -1 on some hacks.
Especially, str subclasses can leak to unsuspected places and create
weird issues (I remember an issue with BeautifulSoup, IIRC, which
returned str subclasses which kept whole HTML trees alive: by passing
those str objects around you would create yourself a huge memory leak).
