You're seeing ghosts. It's trivial and very quick to check if a range
of numbers is sequential.
If it's sequential, you can use your optimized range function, if not,
get the hits one by one. For the later you need a function anyway.

Adding a proprietary extension over such a non-issue is rather sad.
