[design of a bitwise binary library]
(This would all be so trivial in an OO language. Just make an Encoder
object that updates its own state internally and talks to a Source
object and a Destination object for its data...)
I guess it's on the same level of trivialness

Sounds interesting. How does this compare to the uvector library?
IIUC, uvector is based on an older version of the DPH libraries and only
provides unboxed arrays. On the other hand, it's much

Cabal itself is a special case; you need the same version of Cabal
already installed to install it via Cabal...

I also wondered about that. Maybe a '--haddock' flag for 'cabal install' ?
Hi all,
I just noticed that a tiny change to the program which I posted recently in
the More idiomatic use of strictness thread causes a space leak.
The code is:
{-# LANGUAGE BangPatterns, PatternGuards #-}
import Data.List (foldl')
import Data.Char
split delim s

Then again, we don't do fuzzy matching, only completion
of partial identifiers and suggesting possible qualified

Agreed: doing fuzzy matching on

Since you converted everything to lowercase, the string DOC will
never appear in the text, resulting in a single huge document.

Hey everyone,
We started working on a client [1] for the sphinx full-text search
engine [2], which is a very fast full-text search engine that has
either SQL or XML as a backend. While our version is far from done (it
only supports the query command, and a limited number of parameters),

The communication with Sphinx is done using a quite low-level binary
protocol, but Data.Binary saved the day: it made it very easy for us
to parse all the binary things. Especially the use of the Get and Put
