Re: more on interface inheritance issues

Imagine you write code that assumes to have a A object. So you call doSomething() with only 2 arguments. If you now pass to this code a B object, you will have an error because $arg3 is not provided. So adding arguments to an overloaded method should only be done if the additionnal arguments have a default value. Stephane
