It seems there is clearly a need for something of the sort to go into HOL/Library. Maybe it could be completely independent of Poly_Mapping, and the latter perhaps could be rewritten in terms of it.
Now who is volunteering to do this? I could certainly rewrite my "Frag.thy" to use the material I sent out yesterday and make independent of Poly_Mapping, but would that meet everyone's needs?
