Also, I don't really care about a claim that says you could write it faster. That's borderline meaningless in my work unless you're talking about an order of magnitude difference, and I sincerely doubt that. Ah, fair point. If there is no benefit to writing software faster, then yes, the discussion is moot. Apologies if it sounded like I was being a dick. I meant to come across as a “player 2 has entered the game,” but it probably just sounded annoying. I’ve been reimplementing some C projects in LuaJIT (more specifically, a dialect of Lisp that compiles to LuaJIT), and it certainly feels an order of magnitude less overhead to get work done. Perhaps it would be interesting to bind the CSV crate to LuaJIT, and then do a direct translation of XSV. The original discussion was about CLI tools, which is one area that scripting languages excel in, and isn’t necessarily enhanced by the benefits of static typing. Creationix has done a lot of excellent work in popularizing LuaJIT’s benefits: https://github.com/luvit/luvit https://github.com/luvit/luvit

It is interesting how perspectives change things, because I wouldn't be altogether surprised by that actually. I've used both C and Lua quite a bit myself (although not too much recently), and I can believe that. But if you substituted C for Rust, then I would look at it with great skepticism. That is, I don't see it as types-vs-not-types, but memory-safety-vs-not-memory-safety in addition to having a ecosystem that is very easy to draw on in a granular way. And I didn't think you were too annoying. :-) Building an ffi layer over the csv crate would be cool. It would probably be easiest to do it over csv-core, and then build up the convenience abstractions on the C side (or perhaps even at the Lua level) and therefore avoid the csv crate entirely. csv-core will be simpler because it is designed to work in `no_std` environments, which means it never uses platform specific routines and never allocates. Still though, you'll probably need to find a way to amortize allocation on the Lua side. > and isn’t necessarily enhanced by the benefits of static typing Yeah, I mean I obviously very very very very strongly disagree. We are clearly polar opposites here. If I never write anything substantial in a unityped language again, it will be too soon.
