Yes, it looks like we will need something like that.

Note that we already have such object in tests. It's accessible as 
testObj in scripts and implemented in run.c (mostly testObj_GetDispID 
and testObj_InvokeEx). We could probably have a single dispid for 
multiple keyword identifiers there to simplify things.
