You are right. Given the rules marked with asterisks below your
examples would be legal.
EnumDeclaration:
* enum EnumTag EnumBody
* enum EnumBody
enum EnumTag : EnumBaseType EnumBody
enum : EnumBaseType EnumBody
EnumBody:
* EmptyEnumBody
EnumMembersBody
EmptyEnumBody:
* ;
Going by the description on the linked page EmptyEnumBody should
probably be something like this:
EmptyEnumBody:
EnumMember ;
Although going by examples [2] from Andrei's book ("The D
Programming Language"), it seems the following is valid:
EmptyEnumBody:
EnumMembers ;
2. The example from p.69 [TDPL]. It seems to be missing a colon
after "enum".
enum size_t g_maxDataSize = 100_000_000, g_maxMemory =
1_000_000_000;
I hope someone can clear up what is and isn't a valid enum.
