Module Desugared.AstSource

Abstract syntax tree of the desugared representation

Sourcemodule Pos = Utils.Pos
Sourcemodule Uid = Utils.Uid

Names, Maps and Keys

Sourcemodule IdentMap : Map.S with type key = String.t
Sourcemodule RuleMap : Map.S with type key = RuleName.t
Sourcemodule RuleSet : Set.S with type elt = RuleName.t
Sourcemodule ScopeDef : sig ... end

Inside a scope, a definition can refer either to a scope def, or a subscope def

Sourcemodule ScopeDefMap : Map.S with type key = ScopeDef.t
Sourcemodule ScopeDefSet : Set.S with type elt = ScopeDef.t
