IIRC you can open "concrete" generics, but not "open" ones: In plain english this means you can add methods to List<string> but not List<T>.
This is essentially because List<T> isn't a real type in the CLR, it's basically some metadata that can be used to build a real type when the T is supplied. You could as an alternative add methods to the underlying non-generic IEnumerable interface, but then you'd have to do some run-time reflection to figure out that your List is actually a List<string>... This is probably not nice. In theory when CLR4 lands and has support for co/contra variant generics, List<object> should match List<string> and everything else, but I don't know if IronRuby would also work for this?
