Loops are essential for readable code. There is no problem with allowing loops in conjunction with time limits, that we don't have already with complex templates. In fact, time limits for complex templates would be an improvement over the system of expansion limits we have at the moment. Recursion can give a long running time even if the depth is limited. By calling the function multiple times from its own body, you can have exponential time order in the recursion depth. -- Tim Starling _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
