This fails

fricas
(1) -> (Integer,Float)
LISP output: (UNPRINTABLE UNPRINTABLE)
Type: Tuple(Type)

fricas
Tuple Type
LISP output: (UNPRINTABLE)
Type: Tuple(Category)

But this works

fricas
List Type

\label{eq1}\hbox{\axiomType{List}\ } \left({\hbox{\axiomType{Type}\ }}\right)(1)
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); } }

      Use the system command )set compiler args to change these 
      options.

#include "axiom.as"
^
[L1 C1] #1 (Error) Could not open file `axiom.as'.
The )library system command was not called after compilation.

fricas
aInteger:=make()$AldorDomain(Integer)
There are no library operations named AldorDomain Use HyperDoc Browse or issue )what op AldorDomain to learn if there is any operation containing " AldorDomain " in its name.
Cannot find a definition or applicable library operation named AldorDomain with argument type(s) Type
Perhaps you should use "@" to indicate the required return type, or "$" to specify which version of the function you need.

And it nearly solves the problem!

fricas
a:=(Integer,Float)
LISP output: (UNPRINTABLE UNPRINTABLE)
Type: Tuple(Type)

Except:

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

causes Axiom to abort.
