Comment (by yakimun):

 The `const` keyword acts in the same way as `enum` with a single value.

 Our implementation of validation of `enum` was improved in #51911 to
 handle values of different types correctly. These changes bring the new
 function `rest_are_values_equal`, which correctly checks the equality of
 two values.

 I suggest implementing `const` validation using the
 `rest_are_values_equal` because it will provide more consistent results.
 The implementation of such a proposal is attached as a PR.
