In short: none. I opted to mangle Magnus' file in a minimum invasive fashion, and @pyqtSlot was one weapon in his quest to get the thing behave... IMHO, after getting used to it, it's usefulness is two fold: it nicely documents the slots in your classes, and helps to disambiguate/fix those cases, were it is needed. E.g. there are some not so obvious cases in esoteric usage pattern of webkit with javascript/PyQt interaction: http://www.riverbankcomputing.com/pipermail/pyqt/2010-November/028600.html > 2. Where could one look up the code for this decorator? http://www.riverbankcomputing.com/static/Docs/PyQt4/html/new_style_signals_slots.html#the-pyqtslot-decorator > Thanks for your forever careful care of "simple" questions - there is > nothing simple when one does not know how to get it working!

Finally, they've given up, since they failed to cope with the need to redesign/rewrite the whole thing for the third time (in order to deal with the html/java/javascript/browser evolution).. I cannot qualify their development process, but I imagine, that sustainability of PyQt code is a couple of magnitudes above that level, even if factoring in sip v2 to v4, (Py)Qt v3 to v4 and python v2 to v3 advancements from that time.
