I've written this into my code and it works perfectly! :-) I'll tweak it a bit and get it working with the other features in my module. But that's exactly what I was after. Big ++ !!!

I'm just running a benchmark now to see a comparasion against the alternative solution of returning files as arrays.

I intend to leave both methods in the module so it gives the user the choice of streaming or returning via arrays.

Here are the benchmark results:

         Rate stream  array
stream 76.1/s     --   -14%
array  88.7/s    17%     --

         Rate stream  array
stream 79.8/s     --    -5%
array  83.9/s     5%     --

         Rate stream  array
stream 72.2/s     --   -10%
array  80.2/s    11%     --

As you can see returning via array's is faster.

Once again a big thank you!
