I agree options are good as no single solution fits everyone, but I feel I too often hear the sentiment that school/uni/courses is useless. And that is just not true.
I found it understandable and clear. Pocket flow looks cool, although that magic with - >> operators seems a bit obtuse... Also, I think "simply" is a trap - an agent might be modeled by a graph, but that graph can be arbitrarily complex.
What about my of decades worth of snippets, custom commands, templates for all the journals, my bib files, and of course my published works that I borrow pieces from? I should replace that with something nonfree that I have to learn from scratch? Howabout you do you?
Cool, the link is helpful, and the package is pretty cool. I'd just add that the examples are simple and be done with it, you can revisit with more later. Keep writing :)
I didn't find a link to the package in the article. It seems to be a quite capable package, and the given two examples that are trivial to solve analytically don't really do it justice.
