Fine to implement something. But I would wish that the language implemented actually looks like Lisp or Scheme.

Currently this claims to be Lisp, but it is some strange version of it.

Using a Scheme or Lisp has a lot of advantages:

* one can compare it with other actually working implementations

* there is already a wealth of material to learn from or where code could be reused

* many books exist

* the language actually has already got some thought

A good example is the book on Scheme 9:
