That's pretty much just declaring manifest constants with braces so that you
don't repeat the keyword enum a bunch of times.
enum
{
a = "foo",
b = "bar",
c = "baz";
}
is identical to
enum a = "foo";
enum b = "bar";
enum c = "baz";
and it will even let you mix types, e.g.
enum
{
a = "foo",
b = 42
}
which you can't do with actual enums. You're not declaring a new type.
You're just declaring a bunch of constants. They're really not enums in the
classic sense, and for the most part, folks around here aren't going to call
them enums. If anything, a number of folks complain that the keyword enum
was reused for manifest constants. I don't know why the documentation has a
section for "anonymous enums" separate from manifest constants, since
they're really not a different thing, and AFAIK, pretty much no one calls
them that - though at least they're right next to the documentation for
manifest constants.
