By default
make-instance
checks for valid initargs in LispWorks, signalling an error on an invalid call. However, in a delivered application this behavior may not be useful.
Initarg checking in the delivered application is controlled by the
deliver
keyword :make-instance-keyword-check.
For more information about
make-instance
initarg checking, see the
