[elephant-devel] Question about psets and examples shown in tutorial

[wgl]

I am using sbcl 1.0.30, and latest elephant (the alpha 1.0) bdb 4.7 and
am trying to do the examples shown in
http://common-lisp.net/project/elephant/doc/Persistent-collections.html#Persistent-collections to work, and it seems that the double parens around the friends slot def might be a typo.

In any case, with my example using a very similar definition using the
pset approach, the make instance of the persistent class gets "Elephant
deserialization error deserialize fubar!".

Any recommendations would be appreciated.
