For my introductory Compiler Construction class, I have been giving the students a project to write a simple compiler for a toy, single- inheritance object-oriented language. We give them a set of classes implementing an AST for the language and a type checker as well. The students write (1) a scanner and parser to build the AST; (2) a translator from AST to LLVM; and (3) a couple of
