   Syn: Plan; project; contrivance; purpose; device; plot.

   Usage: {Scheme}, {Plan}. Scheme and plan are subordinate to
          design; they propose modes of carrying our designs
          into effect. Scheme is the least definite of the two,
          and lies more in speculation. A plan is drawn out into
          details with a view to being carried into effect. As
          schemes are speculative, they often prove visionary;
          hence the opprobrious use of the words schemer and
          scheming. Plans, being more practical, are more
          frequently carried into effect.

                He forms the well-concerted scheme of mischief;
                'T is fixed, 't is done, and both are doomed to
                death.                            --Rowe.

                Artists and plans relieved my solemn hours; I
                founded palaces, and planted bowers. --Prior.

Scheme
     
         (Originally "Schemer", by analogy with {Planner}
        and {Conniver}).  A small, uniform {Lisp} dialect with clean
        {semantics}, developed initially by {Guy Steele} and {Gerald
        Sussman} in 1975.  Scheme uses {applicative order reduction}
        and {lexical scope}.  It treats both {functions} and
        {continuations} as {first-class} objects.
     
        One of the most used implementations is {DrScheme}, others
        include {Bigloo}, {Elk}, {Liar}, {Orbit}, {Scheme86} (Indiana
        U), {SCM}, {MacScheme} (Semantic Microsystems), {PC Scheme}
        (TI), {MIT Scheme}, and {T}.
