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.
