The ipython python shell has a wonderful feature, whereby you can type:
foo??
and see the text of function foo.
Does scheme (in particular, MIT scheme), have anything like this?
I want to be able to say
(define (foo x) (* x x))
and later view (or even operate on) the list (* x x).
Is there a way to do this?
Not by default in any Scheme I know. What you can do is define a macro that does what “define” does and in addition stores the body of the function in a hash table or an alist or whatever. That will only work on code that you control, of course.
