In my simple tests, that takes 1.8x as long as the original solution. Better than the itertools solution, when "func" is short and fast. I think the solution here would worse if func was more complex. Either way, what I am still wondering is if people would find a built- in implementation useful? -Brad -- http://mail.python.org/mailman/listinfo/python-list
