Not really. You exclude the "self" first argument of a static method. The first argument of a class method is where the class is passed. The reason that "self" is now excluded when defining interfaces comes from considering who reads interface definitions. By their nature, interfaces are meant to be read from the "outside"; from beyond the facade. The "self" attribute of methods is an implementation detail, and is not a concern of those who make calls on an interface. With Python2.2, you can demonstrate this by defining a class that has static methods only, but which still satisfies some interface definition. The "self" argument need not occur at all. -- Steve Alexander _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
