[Ironruby-core] Casting Objects (COM Interop) addendum

COM Interop is not supported in IronRuby. COM objects are not easily reflectable. It *can* be supported. See http://blogs.msdn.com/shrib/archive/2008/07/30/idispatch-support-on-in-ironpython-beta-4.aspx for how IronPython does it. However, IronRuby has not done the equivalent work yet. We will get to it at some point, but as noted in http://www.ironruby.net/About/Roadmap, its low priority for now as there are more important scenarios we need to nail first.

Subject: [Ironruby-core] Casting Objects (COM Interop) addendum
As a follow up to my last message, I wrote a small util method, as follows:
public static class Util
public static T Cast<T>(object o)
And then try to call it from ruby:
x = Util.method(:cast).of(ICanDoStuff).call(mycomobject)
However, the Util.method(:cast).of(ICanDoStuff) fails with this error:
c:\NB\DLR\18015\Languages\Ruby\Src\IronRuby.Libraries\Protocols.cs:405:in `ToType': invalid value for Class: ProxyLi
from c:\NB\DLR\18015\Languages\Ruby\Src\IronRuby.Libraries\Protocols.cs:386:in `ToTypes'
from c:\NB\DLR\18015\Languages\Ruby\Src\IronRuby.Libraries\Builtins\MethodOps.cs:75:in `BindGenericParameters'
from :0:in `of'
Util.method(:cast).of(String) works fine however - is this because I'm trying to pass in a .NET interface (which lives in an auto-generated interop dll built by tlbimp) rather than a class?
Any help is much appreciated
