Does VM = interpreter?
Are you saying implementing a toy Python interpreter is not any harder
than implementing a toy Scheme interpreter?

I don't understand why you think that.
The Python grammar is much more complicated.  Python ASTs are much
more complicated.  Parsing Python files with the whitespace is harder.
Please prove me wrong.  I hope you are right.
