Very neat and practical idea, IMHO! I miss "break N" on occasion in C++. I don't ever remember wanting "continue N" but for the sake of consistency it would fly for me. Alex Programming would be some

Hi, I wrote something that may be useful. It compiles but it isn't tested yet. It's a function lua_xcopy that copies n lua values from one lua Stack to another, like lua_xmove does. But contrary to l

Yes! But it is not optimal for Lua, I made it as a prototype for an algorithm to be implemented in C. Well, it might give ideas, or just show what not to do... :-) -- Philippe Lhoste -- (near) Paris

Hello lua-l, I was learning the coroutines TS (which should be coming to C++20) the other day, and realized it can be used to implement a yieldable/resumable `lua_CFunction` without having to manuall

The two fannkuchs just have a different output. The benchmarks are rather short, so I'm attaching them here for future archival. You get nsieve-bit as a bonus. Run them with a scaling factor of 7 for

If you can permit tricky code, you can achieve a little better speed by parsing numbers manually using string.byte(). Parsing of large numbers can be slowed down by this way, but I suppose this effec

That's easy to implement if you have already have a parser that gives a table `headers` and a string `body`, e.g. the one in stdlib which is basically the same as the one on LuaWiki. See attachment.

That's a real deal. I find 'continue' and 'break N' both very useful in certain situations. I think there also were situations where I wanted 'continue N' that would act similar to 'break N'. 'Redo'

I don't see why "break [N]" is a complication. Want to exit a nested loop, use 'break [N]' otherwise, use 'break'. If you absolutely dislike 'break [N]' and 'continue [N]' on philosophical grounds, u
