 which case it remains `ref`. If the automatically dereferenced value is still a reference,
 it is dereferenced and this process repeats.
 
+Move bindings and reference bindings can be mixed together in the same pattern, doing so will
+result in partial move of the object bound to and the object cannot be used afterwards.
+This applies only if the type cannot be copied.
+
+In the example below, `name` is moved out of `person`, trying to use `person` as a whole or
+`person.name` would result in an error because of *partial move*.
+
+Example:
+
+```rust
+# struct Person {
+#    name: String,
+#    age: u8,
+# }
+# let person = Person{ name: String::from("John"), age: 23 };
+// `name` is moved from person and `age` referenced
+let Person { name, ref age } = person;
+```
