Scott may know a way of fixing your problem. However, it occurred to me
that what you'd really want is to redefine DEFINE so that you can get
hold of the *original* (pre macro expansion) body.
Something like
(define-syntax define
(let-syntax ([old-define define])
(syntax-rules (lambda)
[(_ x (lambda formals . body))
(old-define x (let ([p (lambda formals . body)])
(set-procedure-propery! p 'body
'(lambda formals . body))))]
[(_ . rest) (old-define . rest)])))
would be great, but doesn't work. Scott, do you know of any way of doing
this in psyntax? It seems to be quite a fundamental shortcoming.
Note that
(let-syntax ([old-define (syntax-rules ()
[(_ . rest) (define . rest)])])
(define-syntax define
(syntax-rules (lambda)
[(_ name (lambda formals . body))
(old-define name (let ([p (lambda formals . body)])
(set-procedure-property! p 'definition
'(lambda formals .
body))
p))]
[(_ (name . formals) . body)
(define name (lambda formals . body))]
[(_ . rest) (old-define . rest)])))
(define (foo x) x)))
*does* work, i.e. afer executing the above,
(procedure-property foo 'definition)
yields
(lambda (x) x)
So one way to approach the problem would be to change the repl and load,
or perhaps just eval, to stuff all expressions into a wrapper like the
above.
