- This question concerns environments and scope chains. We will use the following definition for environments: EmptyEnvironment : empty environment Extend(id, value, old_env) : extend old_env by binding variable named id to value. • ExtendRec(rec_function_name, formal_param, body_expr, old_env): a recursive scope chain with name of function, formal parameter, body of function and the old environment.
