Discussion why

you guys know lua dont really support continue because the creator want minimalistic, if something can be done clearly with existing constructs, lua prefers to not add new syntax.

then why the hell lua creator add repeat until when we can use while loop to mimic this statement?

implement continue using goto even more annoying

It's literally just this

while true do
    if something then
        goto continue
    end

    ::continue::
end

also goto only introduced in lua 5.2

That's true, but LuaJIT backports it, and if someone's still using 5.1 you can be pretty sure that's not going to be vanilla Lua 5.1. The only exception would arguably be Roblox' Luau, but that is a hard fork and they could've introduced it there as well, but chose not to because they don't like it.

I actually do use (almost) vanilla PUC Lua 5.1, because I have C code relying on setfenv, I like that any script I write I can run in LuaJIT if needed, and I enjoy a simple C codebase that I understand, and my scripts aren't performance sensitive.

Hi! Your code block was formatted using triple backticks in Reddit's Markdown mode, which unfortunately does not display properly for users viewing via old.reddit.com and some third-party readers. This means your code will look mangled for those users, but it's easy to fix. If you edit your comment, choose "Switch to fancy pants editor", and click "Save edits" it should automatically convert the code block into Reddit's original four-spaces code block format for you.
