By choffstein:

The reason for having the CompressedBytes type was because uncompress2 requires having the length of the string being passed in, so I was storing that in the zlib_pack struct. Also, it allowed me to create the finalizer to manage memory (though -- I can probably do that anyway -- so it's really just the first point).
