Agda.Syntax.Abstract

The abstract syntax. This is what you get after desugaring and scope analysis of the concrete syntax. The type checker works on abstract syntax, producing internal syntax (Agda.Syntax.Internal).

data TypedBinding

A typed binding. Appears in dependent function spaces, typed lambdas, and telescopes. It might be tempting to simplify this to only bind a single name at a time, and translate, say, (x y : A) to (x : A)(y : A) before type-checking. However, this would be slightly problematic:

1. We would have to typecheck the type A several times.
2. If A contains a meta variable or hole, it would be duplicated by such a translation.

While 1. is only slightly inefficient, 2. would be an outright bug. Duplicating A could not be done naively, we would have to make sure that the metas of the copy are aliases of the metas of the original.

Constructors

TBind Range [WithHiding Name] Expr

As in telescope (x y z : A) or type (x y z : A) -> B.

Projection

Fields
