i think i misled with my question though by not providing enough info -
especially like i'm trying to get the ip address of the client through a
cgi script.

Hi Lawrence,
You probably need to also install the support teachpack file
"bootstrap-common.rkt", which can be found here:

The short answer is that the top-level is hopeless, as Matthew has
discussed at some length here and elsewhere.
If you really need to eval code, can you first put it into a module?

Some more excavation into the docs revealed that the preferred technique is
to use namespace-require for the initial import only, and then use eval
statements for the rest. That helped me resolve a difficult bug. But it
didn't resolve this variable-override mystery, because this:
#lang racket

Are you sure you should be using "include"? Is there a reason why
you're using "include", and not "require"?
If you take advantage of Racket's module system, it should prevent you
from creating import cycles. Have you looked at:

Hi Dear Racket experts,
I once accidentally include a file in itself like:
In foo.scm
(include "foo.scm")
And it causes infinite loop. Maybe this should be forbidden in the language
spec.
Thanks,

in php i can do this:
$ip=$_SERVER['REMOTE_ADDR'];
to find out what the client ip address is.
how do i do it in racket?
i looked at request-client-ip provided by
web-server/http/request-structs
but that seems to require i run the racket webserver.

Suppose x-is-foo.rkt is this:
(module x-is-foo racket
(define x 'foo)
(provide x))
If you open another file and try this:
(require "x-is-foo.rkt")
(define x 'bar)
You'lll get a "identifier already imported" error. OK, that much I
understand.
Here's the question. When you do this:
