In IronPython, we went back and forth over this. On the one hand, the API author might have chosen to make it harder to access the method, requiring a cast like this: App::Cls cls = new App::Cls(); cls.bar(); // syntax error IFoo ifoo = (IFoo)cls; ifoo.bar(); // works OTOH, dynamic languages have no type for variables, and so you don't know if it should be an error or not. ie. How would IronRuby know if the programmer expects a variable to be of type App::Cls or of type IFoo.
IronPython ended up allowing it as long as there was no clash. If there is a clash, you have to use App::IFoo(cls).bar().

There is no public 'bar' method on Cls after all. I think IronPython would require you to say something like App::IFoo::bar(App::Cls.new()) in order to make the interface call explicit. -----Original Message----- From: ironruby-core-boun...@rubyforge.org [mailto:ironruby-core-boun...@rubyforge.org] On Behalf Of Tomas Matousek Sent: Thursday, January 08, 2009 7:56 AM To: ironruby-core@rubyforge.org Subject: Re: [Ironruby-core] Problem calling explicit interface methods Filed bug #23494.
