[Haskell-cafe] Bit streams

[Andrew Coppin]

OK, so today I tried to write my first program using the Binary library. 
And I've hit a snag: It appears the library will only handle data that 
is byte-aligned. So if I try to write three Bool values, it uses three 
bytes, not three bits.

Before I sit down and spend 3 months designing my own library from 
scratch, does anybody know of an existing library that allows you to do 
what Binary does, but with single-bit precision? [I presume Binary is 
byte-aligned for efficiency...]
