+We use `MProd` instead of `Prod` to group values when expanding the
+`do` notation. `MProd` is a universe monomorphic product.
+The motivation is to generate simpler universe constraints in code
+that was not written by the user.
+Note that we are not restricting the macro power since the
+`HasBind.bind` combinator already forces values computed by monadic
+actions to be in the same universe.
