The type for which I am the instance meta.

In Java it was possible to define this interface in such a way that the name method was abstract and implemented by each specific Enum, but Kotlin breaks this mechanism. BUT – we're able to cast this to Enum to get to that field. I believe this code gets copied down into each specific Enum subclass, so the dynamic type check for the cast is trivially eliminated in each case. And worst case, Hotspot will be able to inline calls to this from sites that are known to be Enums.

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Returns an array containing the constants of this enum type, in the order they're declared.
