Hello,

Is there a fasl-write / fasl-load functionality in sbcl ? I'd like to use
these functions to serialize functions and closures, as shown below (using
Franz lisp) :

In a first lisp repl :

CL-USER(25): (let ((hop "hop"))
  (compile (defun hello () (format t "Hello ~a~%" hop))))

CL-USER(25): (excl:fasl-write (symbol-function 'hello) "/tmp/hello.fasl")


In another repl :

CL-USER(8): (funcall (first (excl:fasl-read "/tmp/hello.fasl")))
Hello hop
NIL

Is this possible with sbcl ? I've tried to use sb-fasl::dump-object.


CL-USER> (let  ((out (sb-fasl:open-fasl-output (pathname "/tmp/hello.fasl")
"hello")))
  (sb-fasl::dump-object (symbol-function 'hello) out))

but it refuses to dump the function, with the following message:

"This object cannot be dumped into a fasl file:"

Is there a way to do that, i.e. save function and close in a fasl file with
sbcl ?

thanks,
