enum members = [_traits(allMembers, E)];
seems to work
Or if you want it to stay an AliasSeq, then just use Alias or
AliasSeq on it. e.g.
alias members = AliasSeq!(__traits(allMembers, E));
Given that the result of __traits in this case is an AliasSeq,
I have no idea why the gramar doesn't allow you to just use the
result of __traits directly as an AliasSeq with something like
alias members = __traits(allMembers, E);
but it doesn't. So, you have to wrap it, dumb as that may be.
There's a bug report about it in bugzilla somewhere.

I guess? First search result : D
