261	Union of Sets doesn't work	danirus	danirus	"Given the code:

Real divisibleX8(Real x) { x % 8 == 0 };
Real divisibleX12(Real x) { x % 12 == 0 };

Set rango = Range(0,100,4);
Set rangoDivX8 = Select(rango, divisibleX8); 
Set rangoDivX12 = Select(rango, divisibleX12); 
Set union = rangoDivX8 + rangoDivX12;

Doesn't return the correct union between both Sets."	defect	closed	normal		SetAlgebra	head	normal	invalid
