[IronPython] calling a named def

Hi Lee,

I've come across the same problem with C++/CLI and System::Func. IIRC 
the compiler error is a known bug and it will not be fixed - at least 
for VS 2008.
I worked around the missing/buggy System::Func<>^ by using Delegate^:

Delegate^ obj;
if (scope->TryGetVariable<Delegate^>("MyFunc", obj))
{
   obj->Invoke();
}

Regards,
Christian
