Sorry to take so long to reply. In Git commit 4883bad5afde036fa0b73f75aa3789566a3fb7cb, I have changed #@n to always read as an expression evaluating to the nth hashed object, rather than as the nth hashed object itself. This also fixes other random misbehaviour of #@n:

(list 1 2 3)
;Value 18: (1 2 3)

(pp #@18)
;The object 1 is not applicable.

The following transcript explains the problem:

1 ]=> (lambda (x) 3)

;Value 11: #[compound-procedure 11]

1 ]=> #[compound-procedure 11]

;Value 11: #[compound-procedure 11]

1 ]=> (#[compound-procedure 11] 2)

;The object #[compound-procedure 11], passed as an argument to make-combination, is not an operator expression.
;To continue, call RESTART with an option number:
; (RESTART 1) => Return to read-eval-print level 1.

2 error> ((lambda (x) (x 2)) #[compound-procedure 11])

;Value: 3
