I''m "declining" this one. (I marked it Problem Type': Design - UI, since "Bug" is reserved for problems in which the system doesn''t work "as advertised").'
'
I *do* think it is important for (FMEMB ''A ''B) to cause an error (rather than loop infinitely) -- it relies on fixing all of the other CAR/CDRERR''s in the system, however.'
