just a question

[Moshe Cohen <moco@wisdom.bitnet>]

Why is it not possible to set an array element to the result of
the COMPILE function as in:

 (SETF (AREF ARRAY-NAME 1) (COMPILE NIL #'(LAMBDA () 'F)))  .

The following error message is received:

   Trap: The argument given to the CAR instruction,
    #<LEXICAL-CLOSURE (LAMBDA NIL #) 40303466>,
   was not a locative, a list, or NIL.


It IS possible to do it with an auxiliary variable to hold the
result or by using what I understand as a NOOP:

 (SETF (AREF ARRAY-NAME 1) (EVAL '(COMPILE NIL #'(LAMBDA () 'F))))
