Ideally a new Lua dialect would be capable of compiling to both Lua and LuaJIT. The language is effectively forked, with the fastest implementation (LuaJIT) and the official implementation (Lua) living in seemingly irreconcilable worlds.

You suggested it wasn't possible (or practical), so it seemed worth clearing up that it is indeed possible. It is nice to cut the number of distributed artifacts by a factor of four. Also, depending on third-party repositories full of

I think this technique would not work with the limited API: https://docs.python.org/3/c-api/stable.html#limited-c-api The Limited API has a nice benefit of letting you build artifacts that are compatible with a wi

I don't understand how the counter-proposal makes WebAssembly a worse compilation target. Take the simple example of memory.copy. How is it worse to compile memcpy() to import+memcpy() rather than memory.copy? Why can't a string

In that case, it sounds like `length` on Unicode strings simply shouldn't exist, since there is no obvious right answer for it. Instead there should be `codepointCount`, `graphemeCount`, etc.

I don't think photographs are generally advertised as "open source", because there is not generally a source code form of a photograph. The MIT license doesn't distinguish between binaries and source, but the GPL does.

100 times this. C++ is progressively making more and more of the language and stdlib available at compile time (constexpr, consteval, constinit). Once this is accomplished, there will be two very complicated Turing-complete programming

I went the opposite direction: I used to be in the linear code camp, and now I'm in the "more functions" camp. For me the biggest reason is state. The longer the function, the wider the scope of the local variables. Any cod
