Arguments: &body body
This macro is like progn, in
that is executes the forms in body sequentially, but when a
ensuring-compiled-body form
is encountered in interpreted code, it wraps the code body in a
lambda
, processes it with compile-lambda-expr-in-env,
and funcalls the result.
Here is this macro being used by the Allegro CL implementation of cl:time, as an example of its use:
(defmacro time (form) `(ensuring-compiled-body (excl::time-a-funcall #'excl::time-report *trace-output* #'(lambda () ,form))))
See Compiling individual forms or groups of forms in compiling.htm.
