the environment
necessary for macro expansions. In DEFINE-SETF-EXPANDER
and EXT:DEFINE-SETF-METHOD
lambda lists, one can
specify &ENVIRONMENT
and a variable, which will be bound to the
environment. This environment should be passed to all calls of
GET-SETF-EXPANSION
, EXT:GET-SETF-METHOD
and
EXT:GET-SETF-METHOD-MULTIPLE-VALUE
. If this is
done, even local macros will be interpreted as places correctly.
