Inspect Macros'
"I was trying to use an InspectMacro of the type ((FUNCTION fn) propfn '
fetchfn NIL NIL NIL NIL NIL NIL NIL printfn). I got an error - Undefined'
CAR of FORM (NIL printfn). '
The problem is the handling of the WHERE argument. (See manual 20.15). '
The bug is found in the function \APPLYINSPECTMACRO. The NULL test on '
the where argument is made on the list (where propprintfn) instead of on'
the CAR of that list. That explains the error."'
