I am somehow surprised that Axiom cannot work with multivalues.
(1) -> foo(a: Integer, b: Integer): (String, Integer) == ("sum", a+b);
The constructor Tuple takes 1 argument and you have given 2 .
(1) -> foo: (Integer, Integer) -> (String, Integer)
The constructor Tuple takes 1 argument and you have given 2 .
In Aldor the following program works just fine.

------------ multi.as -------------------------------------
-- Run the program via
-- aldor -grun -laldor multi.as
-- and get the output
--: We call the function foo
--: foo(7, 11) = (Sum, 18)
#include "aldor"
#include "aldorio"
import from Integer;
foo(a: Integer, b: Integer): (String, Integer) == ("Sum", a+b);
main(): () == {
stdout << "We call the function foo" << newline;
(s, c) := foo(7, 11);
stdout << "foo(7, 11) = (" << s << ", " << c << ")" << newline;
}
main();
