Evaluation examples

The symbol "==>" used in program examples is read "evaluates to". For example:

means that the expression (* 5 8) evaluates to the object 40. Or, more precisely: the expression given by the sequence of characters "(* 5 8)" evaluates, in the initial environment, to an object that can be represented externally by the sequence of characters "40." See section 3.3 for a discussion of external representations of objects.
