I wonder how this would compare to Judy arrays. Would anyone like to benchmark this?

https://en.wikipedia.org/wiki/Judy_array http://judy.sourceforge.net

To install the Judy C lib:

  brew install judy
  apt-get install libjudy-dev
Then compile with -lJudy and #include <Judy.h>

Example: http://judy.sourceforge.net/doc/JudyL_3x.htm



Interesting. I wonder how similar a Judy array is to an rrb-tree (relaxed radix binary tree), or if they're the same thing.

An rrb-tree is an effective O(1) time for every category. Scala's Vector type implements one.
