Here's example of TS code:

while (true) continue;

Here's generated code:

--[[ Generated with https://github.com/TypeScriptToLua/TypeScriptToLua ]]
while true do
    do
        local __continue2
        repeat
            __continue2 = true
            break
            __continue2 = true
        until true
        if not __continue2 then
            break
        end
    end
end

TSTL generated unneeded __continue2 = true after break statement.

Seems a bit funny, because darklua can't handle this 😄
