Luna: Visual and textual functional programming language
Well, I&#x27;ve been programming for 20+ years across dozens of languages, and I can&#x27;t understand what a single one of those diagrams is actually doing.<p>But I can grok the &quot;textual code&quot; example almost instantly, so fast that the difference in effort is almost laughable. I find the mental overhead in understanding the diagrams vs. &quot;textual code&quot; (that phrase makes me mentally chuckle each time I read it) is orders of magnitude higher. Sorry, but I simply don&#x27;t buy what they&#x27;re selling (<i>and I say this as someone who lives and dies by the whiteboard</i>).<p>About the only thing out of this that looks actually useful for real-world software engineering is the visual profiling piece. If I were them, I&#x27;d probably throw out everything else they are working on and focus on that single piece alone, because that could be pretty useful.
