It is not just like Land of Lisp, it seems to be just Land of Lisp ported to Racket by a group of students supervised by Conrad Barski and Matthias Felleisen. Barski and Felleisen arent even credited as the primary authors of the book.
Realm of Racket (ROAR) is not a translation of Land of Lisp,
but it is heavily inspired by LOL. Our emphasis is on readers
who have done some programming, possibly in Racket-based
teaching languages but not necessarily so, and who wish to
see the beginnings of Racket. You may wish to check out the
sample chapter on Hungry Henry and compare ROAR to LOL
before you buy. Or borrow the book from a friend to see how
ROAR ends in a chapter on #lang.
The author team really consists of eight students and two
'old' people: David Van Horn and myself. As is tradition in
my lab, young people go first and 'old' people come last on
an author list. Everyone knows us already anyway.
