I'm an efficiency fanatic. Nevertheless, I'd like to know whether or not
there's a way to deconstruct a (mostly) arbitrary type, into tuples, unions,

Hi all,
I am the Debian Maintainer of the haskell curl bindings which is failing

The following toy program consumes either 25MB or 70MB, depending on
whether the line

to 130MB when the print is active vs 25MB when inactive.)
What am I doing wrong?

I tried the cabal install command on Windows 7, and I had to run it
with administrative privileges, otherwise I got access denied (it
failed to create the Haskell folder in C:\Program Files)
Not sure if this is also the case on Vista.
Is this the intended behavior?

Sean,
The answer is, I'm working on a recently semi-released package called
TrieMap.

Might it make sense to try and get the concept of global and user
working in Windows? (It may already, but I noticed that the default seems to
be global.)

You are right, I forgot about callbacks. freeHaskellFunPtr is only
for Haskell functions packaged for usage by the foreign code. Example
from the FFI specification, Section 5.4.2:
type Compare = Int - Int - Bool
foreign import ccall wrapper
mkCompare :: Compare - IO (FunPtr Compare)

Hi all,
I'm trying to use Takusen ODBC on Windows.
I'm using a German WinXP Pro and try to connect to an MS Access database.
As soon as I try to do some inserts the above mentioned exception shows up.
Does anyone know a work around for this?

Greetings,
It is my pleasure to announce version 0.2 of the uvector-algorithms package.
The package so far has implementations of several sorting and selection
algorithms for use on the mutable arrays from the uvector library, as well as
combinators for applying them to immutable arrays.

Existential is a perfect word, because it really is

If you were going to make exists a keyword, I think you would write

It sounds like it's looking for the binary package -- you should
install it using cabal, e.g.
private (per-user) install:

cabal install binary

Hello Günther,
It looks like Access is not using UTF8 as its text encoding. I have
Access at work, so I can look into this at some point.
The ODBC code assumes the encoding is always UTF8. For some drivers
(e.g. PostgreSQL) you must configure the ODBC driver correctly to
provide UTF8.
