| Using a constant (::EMPTY) will only create members that do not have a |
| value explicitly specified, whereas using a function (::empty()) will |
| fully instantiate an instance of the struct and overwrite the members |
| that do not have a value specified. The latter prevents creating const |
| tables because overwiting heap allocated values (even when wrapped in |
| Option<_> and set to None) will first drop them, which is not const. |
