Done.

Understood. I should have been more careful.

Ok.

I'm hoping my revert a few hours ago was quick enough. I understand the
frustration and I can assure you that I won't commit the same mistake
again. At any rate, I've done everything on a branch and tests are
looking good on all libraries that use Fusion (testing done locally).

Now, I need to know what to do next. I'd really rather have this in
but I can understand if it's no longer possible at this point.
