* enhancement: CONS can now stack-allocate on x86 and
x86-64. (Earlier LIST and LIST* supported stack-allocation, but
CONS did not:)
+ * enhancement: nested lists can now be stack allocated on
+ platforms providing stack allocation support.
* enhancement: DEFINE-MODIFY-MACRO lambda-list information is
now more readable in environments like Slime which display it.
