auto tags = tags.flatMap!uniq.array ?
That's another solution. In Phobos a flatMap can be useful (just
as a zip overload that accepts a function to apply on the pairs,
named zipWith in haskell:

I think the right abstraction for your use case is:
auto tags = tags.flatten.uniq.array;
auto tags = tags.flatMap!uniq.array ?
