Abstract syntax tree of the desugared representation

module Pos = Utils.Pos
module Uid = Utils.Uid

Names, Maps and Keys

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

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

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