I need to interface with an application that has an IDispatch (activex/ole/automation) interface.  I can find some threads from 2006 about how painful that was.  I'm suspecting that in the intervening 5 years progress has been made, but I'm having trouble finding it.  The manual says D interfaces are descended from IUnknown, which would help me to CREATE an IDispatch object, but how do I use one that already exists?

I've used Juno[1] in the past for COM programming. The project seems dead, and probably don't compile with newer DMD versions, but you might be able to figure out what it does.
