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.

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.

I never heard of this syntax, is it Delphi only?
Trying this I got Error: Interface type IMyInterface has no valid GUID. What
else do I need to do?
Thanks.

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