I'm new to Ada, and I'm wondering what the bitwise (not logical) Exclusive
Or function is?
Using Gnat, this fails to compile:

with Ada.Text_IO; use Ada.Text_IO;
procedure foobar is
  x : integer;
  y : integer;
begin
  x := 12;
  y := 23;
  x := x xor y;
  put_line(x'img);
end foobar;

Gnat complains:
foobar.adb:9:10: invalid operand types for operator "xor"
foobar.adb:9:10: left operand has type "Standard.integer"
foobar.adb:9:10: right operand has type "Standard.integer"

What am I missing?
