A little known "fun fact" about Arc and Bel. Back when I was implementing Cloudflare's WAF in 2012 I wrote an implementation that targeted Arc rather than Lua (which Cloudflare used extensively). We eventually went with the Lua version but the Arc version did work.

To the question “why?” the answer is obvious: 1 — why not, 2 — because it’s beautiful. Projects like this remind us that programming is also an art, not just about solving business problems. Thank you for sharing, it made my day :)
