the internal constructions for structural and well-founded recursion use plenty of `PProd` and `MProd`, and reading these, deeply nested and in prefix notation, is unnecessarily troublesome. Therefore this introduces notations ``` a ×ₚ b -- PProd a b a ×ₘ b -- MProd a b ()ₚ -- PUnit.unit (x,y,z)ₚ -- PProd.mk x (PProd.mk y z) (x,y,z)ₘ -- MProd.mk x (MProd.mk y z) ``` (This is part 1, the rest will follow in #4730 after a stage0 update.)
