Our PLDI 2011 paper has benchmark results:

Very cool. I'll check them out in detail. In the meantime, I'm still trying to

Thanks for all the helpful suggestions.

Muthukrishnan pointed me to an excellent paper on Bit-Comprehensions (think
set/list comprehensions for bits) in Erlang and we are trying to use similar
