-This error indicates that the compiler was unable to sensibly evaluate a
-constant expression that had to be evaluated. Attempting to divide by 0
-or causing integer overflow are two ways to induce this error. For example:
+A constant value failed to get evaluated.
+
+Erroneous code example:
```compile_fail,E0080
enum Enum {
X = (1 << 500),
- Y = (1 / 0)
+ Y = (1 / 0),
}
```

Ensure that the expressions given can be evaluated as the desired integer type.
