Sometimes, a while statement will just make the thing uglier/more error 
prone.

Take the way of faking a 'continue' statement as an example.  Of course, 
I would rather just have a real continue statement, but in an unpatched 
Lua 5.1.4, this is the prescribed way of faking continue.  (Does Lua 
5.2.0 work3 have the continue statement yet?  I haven't looked.)

-- Using repeat..until
for index = 1, 10 do
    repeat
        if math.mod(index, 2) == 0 then
            break  -- Ugly, fake continue statement.
        end

        print(index)
    until true
end

-- Using while
for index = 1, 10 do
    while true do
        if math.mod(index, 2) == 0 then
            break  -- Ugly, fake continue statement.
        end

        print(index)
        break    -- You must remember to put the break here.
    end
end
