Hi, I've been using Twisted for several months, and have frequently encountered the following problem. In my Twisted apps, I declare services (t.a.service.Service), which then I need to subclass. The problem is I can't call super() on such subclass, since the class Service in twisted does not inherit the built-in 'object' type ("TypeError: super() argument 1 must be type, not classobj"). For now, I can use other form of superclass calling, but that can be error prone. Is there any particular reason why class Service isn't a subclass of object ? It's kind of surprising since Service is designed to be subclassed. Thanks in advance for your help/replies. Cheers, Seb -- Sébastien LELONG sebastien.lelong[at]sirloon.net http://www.sirloon.net
