Name references are pointless? OK, you're the expert ...

Last year I started implementing a Python clone. I stopped the project 
because it meant losing too many features I was used to. Also I had 
doubts whether I could even make it as fast as CPython (which had a 
25-year head start).

I've since introduced some aspects of Python (object references) into an 
existing language, while still keeping name references.

Anyway, what I'm saying is, trying to implement a language is also a 
good way of learning it, especially of finding out how it works.
