i think i know why this is happening.
i have attached a test that has the two versions that i have talked about. the slot override works, but the default-initarg doesn't.
ASDF probably calls change-class, probably from reset-system-class, which invokes reinitialize-instance directly, and somewhere here the default initargs are ignored.
but my CLOS is rusty.
is this a user bug, or an ADSF bug?
