@ibodrov thanks for the feedback on this PR! I'm a maintainer of @pixeebot and just wanted to point out that @pixeebot is not actually using AI to make this change....

Seems like there are a few `miniconda` users in this thread. Just wanted to mention that doing `conda install uwsgi` was a pretty decent workaround for me, but ymmv.

It needs the directives defined in `astropy-helpers/astropy_helpers/sphinx/ext/doctest.py`: https://github.com/astropy/astropy-helpers/blob/05ab056575ca7bfa874d43f8a44657c86a9d9354/astropy_helpers/sphinx/ext/doctest.py#L17-L40

I think I'll defer to @bsipocz or @astrofrog on that one...

I'd be in favor, especially given the fact that we recently discovered some issues with the way that `FLOAT_CMP` interacts with other doctest flags. See #54.

@nden maybe you're thinking about doing `fa['data']` instead of `fa.tree['data']`?

This is potentially related to https://github.com/spacetelescope/asdf/issues/446
