For this and all programming project’s, you are welcome to work in groups of up to three. The names of all group members should appear at the top of the file, and every member should submit the project on blackboard. All team members are responsible for understanding the code submitted in their name. You do not have to keep the same group as the previous interpreter parts. A New Parser This interpreter needs a new parser: classParser.scm As with the previous parser, this one is written for R5RS scheme, and you will need to comment/uncomment some lines to use it with racket. The same lex.scm file will work with the new parser. The Language In this homework, you will expand on the interpreter of part 3 by adding classes and objects (instances of classes) An example program is as follows: class A { var x = 6; var y = 7; function prod() { return this.x * this.y; } function set2(a, b) { x = a;
