FWIW I think I was looking for cases where size(methods(class)) == 1,
rather than size(methods(class)-methods(Object)) == 1 which others
have suggested should be applicable for SAM conversion. This may be a
(small) underestimate, but as Joshua noted, there are plenty of other
SAM candidates in other open-source projects e.g. GCL's Predicate:
