That's a good idea. Might http://akkartik.github.io/mu/html/010vm.cc.html [1] be such a big-picture map? Let me think about how to improve it; I haven't touched it in a while. Further suggestions most welcome.
I was thinking something much simpler. If you were writing a book about Mu what would be the definitions you would print on the back inner cover? A table with two columns - first column being a term and the second column containing its description in one or two sentences.
Could you elaborate on the target audience for the doc you linked to? I am unable to make out whether that doc is intended for serious programmers in other languages coming across Mu for the first time or whether its intended for new comers to programming.
Yeah the intended audience is existing C++ programmers coming across Mu for the first time. For teaching programming I mostly imagine I'll be doing it in person. Mu isn't yet ready for learning programming unassisted.
