I think this might be a bug

set of int: X = {1,3,5} diff (2..5 union 1..0);
set of int: Y = {1,3,5} diff (2..5 union {});
output show([X,Y]);

Playground.mzn:2.42-43:
MiniZinc:
type error: ambiguous overloading on return type of function

Both on edge and latest (2.8.7)

The text was updated successfully, but these errors were encountered:

This variant works on Playground:

set of int: emptySet = {};
set of int: X = {1,3,5} diff (2..5 union 1..0);
set of int: Y = {1,3,5} diff (2..5 union emptySet);
output show([X,Y]);

I doubt that 1..0 should be digested as empty set without warning.
