Question:

Extend the Definelang programming language from this chapter such that it supports a cdefine declaration for a constant define declaration. The goal of adding this new declaration is to define a constant variable whose definition cannot be changed after it is defined.

A cdefine declaration has the following form: $ (cdefine Identifier Exp) Some example usage of this declaration appears here: $ (cdefine R 8.3145) unit

A programmer can use define and cdefine in the same program. For example, the program here shows an attempt to change a constant defined by a cdefine using a define declaration, which also fails: $ (cdefine buffer 0) $ (define buffer (+ buffer 2)) // Producer expression Cannot modify binding for name:
