Thanks for the confirmation. Actually I hoped this would not occur in the
latest version, as Nikodemus Siivola said on 2008-01-15, in reply to what
seems a very similar issue reported by Pascal Costanza: "This seems to have
been fixed at some point during the last 10 months": <

Custom metaclasses are crucial for CLPython. Hopefully someone feels
inclined to fix this SBCL issue.
