I'm glad to see that while seeking reason you are also demonstrating it.

The micro benchmark is just that, and is not as far as I can see testing the sort of iterating process that would happen normally when going through a data set. It simply times the iterator, but does not compare like with like! The question I am asking is if USING 'xrange' to feed a feed a function and use the results is faster than 'urange' simply using the iterator to call the handling function DIRECTLY. To fix this benchmark what I am missing is how the 'yield' approach would be used to build the $result[] array. This may be obvious to some of you, but I'm missing something to help me understand just what is planned here :( -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
