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.
The second argument to the COMPILE function is a lambda-expression, not
a function. You must give COMPILE a quoted lambda expression, which is
implicitly in the null lexical environment, not a closure.
It's essentially a bug that typing at top-level
(compile nil #'(lambda () 'f))
is sometimes treated as synonymous with
(compile nil '(lambda () 'f))
Only the latter is intended to work.
