1583	coops record-printer for instances do not work	Kooda		"As reported on IRC by matijja, coops’ record printer for class instances does not work.

While redefining a record printer for it makes everything work as expected:

From what I could gather, coops uses the record-variant egg to define its `coops-instance` record type.

It appears the egg has not been updated to add the new module prefix of the record symbol, so it registers the record type as just being `coops-instance`, while the `define-record-printer` macro correctly adds the module prefix, making them distinct from each other, the printer is then never used.

If we update the record-variant egg, we also would have to update coops, because it uses `##sys#check-structure` directly."	defect	closed	minor	5.1	extensions	5.0.0	fixed			easy
