@hackage bitvec0.2.0.1

Bit vectors library for Haskell. The current vector package represents unboxed arrays of Bool allocating one byte per boolean, which might be considered wasteful. This library provides a newtype wrapper Bit and a custom instance of unboxed Vector, which packs booleans densely. It is a time-memory tradeoff: 8x less memory footprint at the price of moderate performance penalty (mostly, for random writes).
