Greetings
I've run into a problem on the latest Elephant 1.0 from the darcs
repository, with SBCL 1.0.34 on FreeBSD and 1.0.39 on MacOS.
(make-pset) fails with a deserialization error (steps below). Other
operations like creating and initializing a persistent class, or
adding to the root, work fine. Am I doing something silly?
