Ironruby core - May 2009 - interface generic w/ generic methods

Hi
I''m observing the following behavior when I try to implement a CLR
interface
with generic method definitions.

So let''s say an interface contains the following method definition

public interface IRubyEngine {
     T CreateInstance<T>(RubyClass rubyClass);
}

in ruby
class MyEngine
   include IRubyEngine
end

So far so good nothing has actually been created yet.

MyEngine.new => raises

(master) ? ir

>>> require ''bin/System.Web.Mvc.IronRuby.dll''

>>> class MyEngine
... include System::Web::Mvc::IronRuby::Core::IRubyEngine
... end
=> MyEngine
>>> MyEngine.new

''ExecuteFile'' in type
''IronRuby.Classes.Object$1'' from assembly

implementation.

c:\tools\ironruby\ndp\fx\src\core\microsoft\scripting\Actions\CallSiteBinder.cs:79:in
`BindDelegate''
        from :0
>>> exit
in the console output above it complains about a different method but the
idea is the same. that method def was T ExecuteFile<T>(string path, bool
throwIfNotExist);

Do I put this on codeplex or is that the expected behavior?

Two points: 1) We should probably have a clearer error message in this case. 2)
That seems to be a bug since the behavior is different if IRubyEngine declares
non-generic methods.

Please file a bug on CP with both points.
