Comment:
Thanks for the report. I was able to reproduce this issue, but to be
honest Python3 behavior looks more correctly to me. In both cases
`isinstance()` evaluates an objects, so it is not a matter of laziness. We
could accept this as a bug for Python2, but first of all this doesn't
qualify for a backport and secondly fixing this on Python2 is not what you
expect.
