Re: Question about table.remove.

[ks isaf <ks_isaf@...>]

May be is the reason you had mentioned.

Let's take a look at the examples below:

---------------------

array = {1,2,3}
--Example A:
while true do
  if table.remove(array,1) == nil then
  break;
  end;

  ...
end;

--Example B:
while true do
  if array[1] == nil then
  break;
  end;
  table.remove(array,1);

  ...
end;

---------------------

In some situation, it can simplified the code while "table.remove" accept the index len+1.

But i think example B is more clearly to tell what does this codes do, and can adapt to future changes of lua(maybe table.remove(len+1) will trigger an error one day.)

thx for the reply.
