If Lisp is not a mainstream language, why are we using it as the framework for
our discussion of programming? Because the language possesses unique features
that make it an excellent medium for studying important programming constructs
and data structures and for relating them to the linguistic features that
support them. The most significant of these features is the fact that Lisp
descriptions of processes, called procedures, can themselves be
represented and manipulated as Lisp data. The importance of this is that there
are powerful program-design techniques that rely on the ability to blur the
traditional distinction between
passive'' data andactive'' processes. Aswe shall discover, Lisp's flexibility in handling procedures as data makes it
one of the most convenient languages in existence for exploring these
techniques. The ability to represent procedures as data also makes Lisp an
excellent language for writing programs that must manipulate other programs as
data, such as the interpreters and compilers that support computer languages.
Above and beyond these considerations, programming in Lisp is great fun.
