Comment (by cremona):
This looks pretty good (I have not actually tested it yet though). Alex,
can we not check that the polys define a map to the correct space by
checking that the defining polys of the target (if any) vanish when
evaluated at the tuple of polys defining the map? If that works it would
be worthwhile adding it.
