++ Author: Gabriel Dos Reis
++ Date Create: October 18, 2007.
++ Date Last Updated: December 12, 2007.
++ Basic Operations: coerce, reify
++ Related Constructors: Type, Syntax, OutputForm
++ Also See: Type
Domain(): Public == Private where
  Public ==> CoercibleTo(OutputForm) with
    reify: % -> Syntax
      ++ reify(d) returns the abstract syntax for the domain `x'.
   
    showSummary: % -> Void
      ++ showSummary(d) prints out implementation detail information
      ++ of domain `d'.

  Private ==> add
    coerce x ==
      outputDomainConstructor(x)$Lisp

    reify x ==
      convert(devaluate(x)$Lisp)$Syntax

    showSummary x ==
      showSummary(x)$Lisp
