That wasn't done by me but by GvR (according to svn annotate) in r55818,
presumably during the stdlib porting to py3k. I just copied the line over, not
thinking it wouldn't work for 2.7.

That's just about what I've actually done: I was just curious about the
difference between py3k and trunk :-)
If __builtins__ is an implementation detail which can't be relied on, should the
py3k code be changed to the try: form? Or shall I just remove the checks
altogether, since Unicode should always be there in 3.x?
