 A binding shadowed something it shouldn't.
 
-Erroneous code example:
+A match arm or a variable has a name that is already used by
+something else, e.g.
+
+* struct name
+* enum variant
+* static
+* associated constant
+
+This error may also happen when an enum variant *with fields* is used
+in a pattern, but without its fields.
+
+```compile_fail
+enum Enum {
+    WithField(i32)
+}
+
+use Enum::*;
+match WithField(1) {
+    WithField => {} // error: missing (_)
+}
+```
+
+Match bindings cannot shadow statics:
 
 ```compile_fail,E0530
 static TEST: i32 = 0;
 
-let r: (i32, i32) = (0, 0);
+let r = 123;
 match r {
-    TEST => {} // error: match bindings cannot shadow statics
+    TEST => {} // error: name of a static
 }
 ```
 
-To fix this error, just change the binding's name in order to avoid shadowing
-one of the following:
+Fixed examples:
 
-* struct name
-* struct/enum variant
-* static
-* const
-* associated const
+```
+static TEST: i32 = 0;
 
-Fixed example:
+let r = 123;
+match r {
+    some_value => {} // ok!
+}
+```
+
+or
 
 ```
-static TEST: i32 = 0;
+const TEST: i32 = 0; // const, not static
 
-let r: (i32, i32) = (0, 0);
+let r = 123;
 match r {
-    something => {} // ok!
+    TEST => {} // const is ok!
+    other_values => {}
 }
 ```
