⟨⟩ : ∀ {i} {A : Type i} {{a : A}} → A
⟨⟩ {{a}} = a
{- Identity type
The identity type is called [Path] and [_==_] because the symbol [=] is
reserved in Agda.
The constant path is [idp]. Note that all arguments of [idp] are implicit.
-}
⟨⟩ | core/lib/Base.agdaEach declaration is split into a statement (signature/claim) and a proof (body) that are disjoint
and together form the complete declaration, for proof modeling, autoformalization, retrieval, and
dependency analysis via deps.
