That may be, but it was unfair to get angry at the ASDF maintainers
about this. This is just a pre-existing error that was *manifested*
because of a change in ASDF. It's not our fault that this error
appeared, it's not our fault that the puri library is no longer
maintained, and we can't be expected to avoid releasing improved
versions of ASDF because there exists buggy, unmaintained code in
An apology from you would be appropriate at this point.
