reduction
     
        or "contraction" the process of transforming an expression
        according to certain reduction rules.  the most important
        forms are beta reduction application of a lambda
        abstraction to one or more argument expressions and delta
        reduction application of a mathematical function to the
        required number of arguments.
     
        an evaluation strategy or reduction strategy, determines
        which part of an expression which redex to reduce first.
        there are many such strategies.
     
        see graph reduction, string reduction, normal order
        reduction, applicative order reduction, parallel
        reduction, alpha conversion, beta conversion, delta
        conversion, eta conversion.
