Switch from except' (from racket/unit') to #:except' in 2htdp/private'.
...
This is used by the `function-with-arity' macro, and the use of `except'
looks like something that is better done with a keyword. I think that
this change should be fine since it's a private function.

racket' -> racket/base' switches in htdp' and 2htdp'.
...
All of these look safe. Also, see comment in `2htdp/batch-io' about the
splitting thing (which should probably be revised with the extensions to
`racket/string').
