Scheme 9 from Empty Space

 Scheme 9 from Empty Space reproduces the completely self-contained and heavily commented C and Scheme source code to a full, real-world interpreter for the Scheme programming language. By means of extensive annotations, examples, and numerous figures, it answers a lot of questions about crafting an interpreter, including:
    How does automatic memory management work?
    How is macro expansion implemented?
    How does lexical scoping work?
    How is arbitrary precision arithmetics implemented?
    How does tail call elimination work?
    How are first-class continuations implemented?
This textbook is intended as a practical guide for everybody who wants to take a deeper look at the techniques behind the interpretation of computer programs. It does not stop where other books do, and takes a deep look behind the scenes of a real interpreter.
