I've been writing it for >5 years and I still reach for vectors haha. I think it's my C++ background which makes me a bit allergic to lists. The reality is that if I moved more transducer based solutions this would be a non-factor most of the time. (unfortunately this example doesn't suit transducers very well)

I gotta use transducers, lists and benchmarking more..

Thanks for sharing how you approach these problems
