[racket] Scoped require

Hello.

Thank you for your reply, Eli.
It looks like I need to state my question more clearly.

The trick I'm looking for is how to create a quasi-begin form inside 
which you can use all the other symbols defined in the module, while 
those symbols are not imported into top-level. In fact the only thing 
added to the top level is supposed to be the quasi-begin form itself.

Best regards, Maxim.
