 ///
-/// When environment::use_enum_binary_only_equality() is true, this
-/// equality operator only cares about the value of the enumerator.
-/// It doesn't take the name of the enumerator into account.  This is
-/// the ABI-oriented default equality operator.

-/// When the environment::use_enum_binary_only_equality() is false
-/// however, then this equality operator also takes the name of the
