+## **unusedwrite**
+
+checks for unused writes
+
+The analyzer reports instances of writes to struct fields and
+arrays that are never read. Specifically, when a struct object
+or an array is copied, its elements are copied implicitly by
+the compiler, and any element write to this copy does nothing
+with the original object.
+
+For example:
+
+	type T struct { x int }
+	func f(input []T) {
+		for i, v := range input {  // v is a copy
+			v.x = i  // unused write to field x
+		}
+	}
+
+Another example is about non-pointer receiver:
+
+	type T struct { x int }
+	func (t T) f() {  // t is a copy
+		t.x = i  // unused write to field x
+	}
+
+
+**Disabled by default. Enable it by setting `"analyses": {"unusedwrite": true}`.**
+
