{C : Type u} →
[inst : CategoryTheory.Category.{v, u} C] →
(G : CategoryTheory.Functor C (Type w)) → CategoryTheory.Grothendieck (G.comp CategoryTheory.typeToCat) ≌ G.ElementsThe Grothendieck construction applied to a functor to Type
(thought of as a functor to Cat by realising a type as a discrete category)
is the same as the 'category of elements' construction.
