+An array or slice pattern was matched against some other type.
+
+Example of erroneous code:
+
+```compile_fail,E0529
+let r: f32 = 1.0;
+match r {
+    [a, b] => { // error: expected an array or slice, found `f32`
+        println!("a={}, b={}", a, b);
+    }
+}
+```
+
+Ensure that the pattern and the expression being matched on are of consistent
+types:
+
+```
+let r = [1.0, 2.0];
+match r {
+    [a, b] => { // ok!
+        println!("a={}, b={}", a, b);
+    }
+}
+```
