Isn't it possible to treat functions in Scheme as any other list?

Basically, what I want do to is something like this:

(define (foo) "hello")

(cdr foo)  ; or similar, should return the list ((foo) "hello")

I've found a similar discussion about this, and I feel a bit disappointed if this is not possible with Scheme. If so, why is this impossible? Is it possible in other lisps?

EDIT: Changed (cdr 'foo) to (cdr foo) -- it was misleading. I'm asking, why can't I access a function as a list?
