If you want a fast mutable hash table Gregory Collins (CCed) have been working on a few implementations that beat Data.Hashtable by a large margin. I don't know if they're ready for general use yet (i.e. they haven't been released on Hackage yet).

Hi all,

The code:

 a) isn't finished  b) needs to go through my employer's open-source releasing process

But yes, it currently beats Data.Hashtable by something like 4-6x. I could work on it with some more urgency if people were interested.

I'm very interested! A mutable hashtable is a key data structure in berp, the python compiler that I am writing. Cheers, Bernie.
