I think it is the same as auto return functions. Both auto and
enum in this context are storage classes. In the compiler, it
looks like enum in this context forwards to parse declaration,
just like keywords such as pure, which can then find it is a
function. If I'm reading this correctly, it does set the
manifest constant flag, but otherwise just ignores it and
indeed treats it the same as an auto return value.
So nothing special, arguably just the parser not throwing an
error when it perhaps could.
It would be cool if it was a compile time value though. That way
you could make sure code generating ctfe's were never included in
the binary.
