... still not that interesting, but at this point slightly divergent
from the book:
The book embraces mutability for interpreter state, initially for
tracking whether an error condition has occured.
I avoid this by instead defining an error type and collecting the
error values, to be handled later on.
Notes: So far nothing special, but this is just the beginning of the
book. I like the style it is written in and it has pointed to some
interesting resources, such as a 1965 paper titled "The Next 700
Languages".
