+A binding shadowed something it shouldn't.
+
+Erroneous code example:
+
+```compile_fail,E0530
+static TEST: i32 = 0;
+
+let r: (i32, i32) = (0, 0);
+match r {
+    TEST => {} // error: match bindings cannot shadow statics
+}
+```
+
+To fix this error, just change the binding's name in order to avoid shadowing
+one of the following:
+
+* struct name
+* struct/enum variant
+* static
+* const
+* associated const
+
+Fixed example:
+
+```
+static TEST: i32 = 0;
+
+let r: (i32, i32) = (0, 0);
+match r {
+    something => {} // ok!
