Spexy had a repl, for testing purposes. The >>>> lines are my input, the --> lines are spexy letting me see the Python code it created from my input, and then following that is the result of the evaluation if any.

spexy repl example

[siege@maybe src]$ python spexy.py
>>>> (defun make_pair ()
        (letrec ((value None)
                (getter (lambda () value))
                (setter (lambda (v) (setf value v))))
            (make-list getter setter)))
--> globals().__setitem__('make_pair', (lambda : ((lambda value, getter, setter: ((value.__setitem__(0, None), getter.__setitem__(0, (lambda : value[0])), setter.__setitem__(0, (lambda v: value.__setitem__(0, v))),)[-1], [getter[0], setter[0],],)[-1])([None], [None], [None]))))
>>>> (letrec ((gs (make_pair)))
        (define getter (getf gs 0))
        (define setter (getf gs 1)))

## <lambda>() takes exactly 1 argument (0 given)
>>>> (setter "hello world")
--> setter("hello world")
>>>> (getter)
--> getter()
'hello world'
>>>> (getter)

'hello world'
>>>> (setter "919")

>>>> (getter)
--> getter()
'919'
