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),
}
```

This error indicates that the compiler was unable to sensibly evaluate a

Ensure that the expressions given can be evaluated as the desired integer type.
See the FFI section of the Reference for more information about using a custom
integer type:
