I think the thing that is getting people confused here is GC vs stack. That's certainly what the blizzy "makes GC cry" comment was about. Are you making lots of tables or unique strings? If not, then don't worry about it. Lua manages locals just fine, the thing you need to concern yourself with is generating garbage, which happens when you make lots of local tables or unique strings. The only thing that really matters with were locals are declared is scope, not performance.

do
    for k,v in pairs(largeTable) do
        local var = someFunc(k,v)
        -- do something with var
    end
end

compared to

do
    local var
    for k,v in pairs(largeTable) do
        var = someFunc(k,v)
        -- do something with var
    end
end

Okay, I think I did not get it right... are these two now equivalent (functional ofc, but also performance)?

I think I read not, but I doubt this... If they are not, why exactly?
