This fails

axiom

(Integer,Float)

 LISP output:
(UNPRINTABLE UNPRINTABLE)

Type: Tuple(Type)

axiom

Tuple Type

 LISP output:
(UNPRINTABLE)

Type: Tuple(Category)

But this works

axiom

List Type

$\label{eq1}\hbox{\axiomType{List}\ } (\hbox{\axiomType{Type}\ })$

Type: Type

The following domain called Domain provides some of the missing functionality. It is based on AldorDomain by Peter Broadbery who writes:

  [One] can still do some useful things with them by disguising
  the fact that they are domains, so in aldor have a type and
  your aldor programs can return this to axiom.

For example:

aldor

#include "axiom.as"

AldorDomain(T:Type): with {
      make: () -> %;
      coerce: (%) -> OutputForm;
} == add {
      Rep ==> Type;

      make(): % == per T;

      coerce(t: %): OutputForm == {
              import from SExpression;
              devaluate(t pretend SExpression)::OutputForm
      };

      import {
              BOOT_:_:devaluate: SExpression -> SExpression;
      } from Foreign Lisp;

      local devaluate(s: SExpression): SExpression == {
              BOOT_:_:devaluate(s);
      }
}

And it nearly solves the problem!

axiom

a:=(Integer,Float)

 LISP output:
(UNPRINTABLE UNPRINTABLE)

Type: Tuple(Type)

Except:

  \begin{axiom}
  select(a,1)
  \end{axiom}

causes Axiom to abort.
