Hi, lisp in lisp evaluator is the simplest evaluator you can build, because lisp uses list to represent its program, and all lisp dialect provide `read` function, so if you want to build an evaluator, you could just use this function and don't need to do lexical and syntax analysis. This is the power of lisp, so I can't see why you can't do it. The difficult part is adding core library support, this will take a lot of time and code to implement.
