structural recursion
     
        The process of transforming an expression by expressing its
        structure as a syntax tree and applying a certain
        transformation rule to each kind of node, starting from the
        top.  Rules for non-{leaf node}s will normally return a result
        which depends on applying the rules recursively to its
        sub-nodes.  Examples include {syntax} analysis, {code
        generation}, {abstract interpretation} and {program
        transformation}.
