Once you do this, IIRC, all of the examples in TSPL4 work in DrRacket
except for those that use set-car! and set-cdr!, since Racket (by
design) does not allow mutable pairs.

I played some with trying to use those examples with Racket's mcons
mutable pairs, but didn't find any clean way to get there from here,
since enough other things get broken by the fact that cons pairs and
mcons pairs are not interchangeable.
