FYI, asdf-install metatilities results in the following error:
Cannot IMPORT "FIND-OR-CREATE-CLASS" from package "METATILITIES"
I believe the error happens when containers-test is loaded. This is probably because find-or-create-class is now in DYNAMIC-CLASSES, not in metatilities.
Sorry if this isn't a proper medium to report this error. Thanks again for giving us great software for free!
