Bonus: rename the library "immutable-long-map", then you can have a section
in the readme titled "why the long map?"

Correct. I'll clarify that I mean 64 bit integers in the readme.

Never mind, look like you mean integer in the generic sense and you are using
longs, right?

I could represent the map {0 :foo, 100 :bar} as an array, but it would
have to be a million element array with a lot of empty space. This would be
(maybe) faster w.r.t. lookups, but would be vastly slower for enumerating
entries, merging other maps, and adding keys that are larger than the
"it's an immutable map that can only have positive integers as keys" -- Like
an array?

The one interesting aspect of this is that it has an efficient merge
mechanism, which means it plays better with Clojure's reducer fra
