The Seasoned Schemer
Friedman and Felleisen'sThe Seasoned Schemerpicks up where their book,The Little  Schemer,left off and focuses on the myriad uses of functions in Scheme. Using the same dialogue  format asThe 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.
