I'm reconsidering this. When would the immediate value of a varobj with
children be of interest? It certainly doesn't seem to be for
non-pretty-printed varobjs.

Not at present. We could add one, of course, but I have been trying to
push the current simple design as far as it would go. Partly this is
just stubbornness but also I do think that simplicity has some intrinsic
virtue, at least when you can get away with it.

Yeah. I'll do this.

Ok, will do.
