+This error indicates that a static or constant references itself.
+All statics and constants need to resolve to a value in an acyclic manner.

+For example, neither of the following can be sensibly compiled:

+const X: u32 = X;
+```

+const X: u32 = Y;

 This error indicates the use of loop keyword (break or continue) inside a
 closure but outside of any loop. Break and continue can be used as normal
