Agda.TypeChecking.Names

Description

EDSL to construct terms without touching De Bruijn indices.

e.g. if given t, u :: Term, Γ ⊢ t, u : A, we can build "λ f. f t u" like this:

runNames [] $ do -- open binds t and u to computations that know how to weaken themselves in -- an extended context

t,u
<- mapM open [t,u]
  • - lam gives the illusion of HOAS by providing f as a computation
  • - It also extends the internal context with the name "f", so that
  • - t and u will get weakened in the body.
  • - Then we finish the job using the (@) combinator from Agda.TypeChecking.Primitive

lam "f" $ f -> f @ t @ u
