Calls to
cl:+
,
cl:-
and
cl:*
with more than 4 arguments are now optimized with the
float 0
and
safety 0
declaration. This improvement was actually made in LispWorks 5.1, however the documentation in LispWorks 6.0 and earlier stated that the optimization would not happen with more than 4 arguments.
