Well, I did skim a little bit through Eve's source code, specifically the files in
https://github.com/witheve/Eve/tree/master/src and subs, and the first thing that stroke me was: it's not literate. As a matter of fact, it doesn't have more comments than an average code base, maybe even less.
Why? Where is the prose? What makes programs supposed to be written in Eve different from Eve itself?
