I'm totally impressed and grateful that you tracked this down!

(It was i386 for libanyevent-perl 5.271-1.)

I've uploaded libanyevent-perl 5.271-2 right now with these changes.

If it works out we need to ask for a freeze exception.
(Cc'ing the release team as a "heads up".)

Agreed, that was just an ugly, desparate (and also obviously wrong)
attempt to find out what's going wrong or beat at it ...

I guess if the plan works out (i.e. libcoro-perl builds with the
newer libanyevent-perl), a freeze exception (removing the newly added
cruft from debian/rules) would be nice.
