[Haskell-cafe] Re: Mining Twitter data in Haskell and Clojure

[John Van Enk]

Would it be possible to use an IntMap instead of your OrdMap? Perhaps zip
your users with [0..] and key off the integer?

As a side note, I threw this package onto Hackage a while ago and may suit
your needs if you decide to move to something like IntMap:
http://hackage.haskell.org/package/EnumMap

It does have a performance hit over an IntMap, but I'm not entirely sure how
large it is.
