be picky and check explicit implementation name

- the previous code tried to avoid breakage from changing an
  implementation detail
- this turns out to be harder than expected in a Python2/3 portable way
- also it would mean the intentional drive-by documentation of the
  expected implementation name will at least not bit rot now
