Exercise 4.10: By using data abstraction, we
|
||
|
|
were able to write an eval procedure that is independent of the
|
||
|
|
particular syntax of the language to be evaluated. To illustrate this, design
|
||
|
|
and implement a new syntax for Scheme by modifying the procedures in this
|
||
|
|
section, without changing eval or apply.
