In SMP LispWorks, access to non-constant special variables is a little slower than in previous releases. You can speed up such access by declarations of the special symbol, normally by using
cl:proclaim
or
cl:declaim
with one of the new declarations
hcl:special-global
,
hcl:special-dynamic
and
hcl:special-fast-access
. See "Optimizing your code" in the
LispWorks User Guide and Reference Manual
