where does the namespace alias fv come from?

The original documentation by Michal 🙂

Seriously, I do not know.

This is absolutely fantastic!

I perfectly understand its use now :)

I feel confident that I can pick it up when I need it

i haven't seen the previous version but this is quite nice in explaining rationale, etc

In the person who complained before :)

I did recall there was someone commenting on it, but not who. Glad the changes worked for you. I looked at it and realized it was previously written from the perspective of one who knew Clojure internals fairly well already.

I asked as well, to see whether it would be useful for anything at work (it wouldn't, it seems).

So, yes, thank you for the clarification @U0CMVHBL2 !

Sure, its use cases are fairly limited. If my plans for world domination come to fruition, I hope to make it even faster than Clojure's built in vector data structure. But that is a big question mark, and a fair chunk of work away from now.

would love a #hacktoberfest on a data structures type project in contrib with an active maintainer 🙂

I'm not sure what is involved there, but the weird thing is that anything that isn't already fixed, is also on the edge of what I know how to do.
