The Seasoned Schemer (MIT Press)

Friedman and Felleisen's The Seasoned Schemer picks up where their book, The Little Schemer, left off and focuses on the myriad uses of functions in Scheme. Using the same dialogue format as The Little Schemer, the authors demonstrate how Scheme's flexible facilities for handling functions give the program so much variety and power. Along the way, the authors also present a variety of other more sophisticated language constructs.
