[movitz-cvs] CVS update: movitz/losp/muerte/inspect.lisp
by Frode Vatvedt Fjeld 24 Sep '04

24 Sep '04

Update of /project/movitz/cvsroot/movitz/losp/muerte In directory common-lisp.net:/tmp/cvs-serv31289 Modified Files: inspect.lisp Log Message: shallow-copy had a bug wrt. vectors, because the elements were copied by considering the original vector as a sequence, and therefore any elements beyond the fill-pointer were not copied. Also, the new copying strategy should be considerably faster.
