Great, I got this working now.
This is one small step better because the only string identifier used in code
for the interface is in the declaration itself so if the name of the interface
gets changed I'll get compiler warnings when I try to invoke it.
Thanks.

I'm getting an identifier not found error with the procedure "Supports". Where
is this defined?

You could also try the Supports() method. eg:

Now it works! That seems redundant to declare an identifier when the interface
name itself is unique. I would think the CORBA style identifier should default
to the name of the interface.
Thanks, I wanted this feature for a while now.

The sintaxe i posted is for COM interfaces.
For CORBA interfaces do
IMyInterface = interface
