Hi,
I downloaded and installed ghc-5.02.2-i386-unknown-linux.tar.bz2 on my
RedHat Linux 6.2 box (because RPM won't install the relevant RPMs).
However, when I run ghci, I get the message ... GHC ... 5.02.1 ...
What do you think is happening here?
Best Regards,

Just leave out the existential in your defn of D!
The (C a b) in the defn of f will do the job.
But your example nevertheless does expose a delicate interaction in the
type checker. 5.02.2 happened not to expose the functional
dependency, so it simply use the (C a b) that f provided.

You never responded to my question about MVars...

The version that I release is based entirely on LS

useful for customer.

Hi Bernie,
I've been playing with the FFI in GHC 5.02.2
I'm not sure if I'm using it correctly because I get a space leak
in my program.
I just tried your example and it seems to run in constant space here
with 5.02.2. The code looks fine - this isn't something we really
envisaged people
A while back I asked how to make the Ref's from Koen Clasessen's PhD
thesis Ord-able for the purpose of making them keys for efficient
finite maps.
Koen quickly responded with a clever implementation which attaches the
values to the keys. While I don't rule out eventually making use of

I'm delighted and impressed that you have completed the Object I/O
port, but I don't think I agree with you about the MVar/LS issue.

I don't know how to make existentials know about functional
dependencies. In the type system that GHC implements, your
example fails, and I don't see any meaningful way to make it
succeed. But maybe someone else does.

Nice. :-)

Having written a Haskell LDAP interface, this is something that worried me
but I never got to the bottom of. I've cross-posted this to haskell
(hopefully the right place). There was some discussion of replacing Char by
a type for raw bytes / octets but I'm not sure what happened to it.

Folks
Following a good deal of email I now propose to
DO NOTHING
to the rules defining do-notation in the Haskell 98 Report.
That means that GHC and Hugs, and nhc perhaps, should
change so that they actually implement the do-notation
translation rule
do {e ; stmts} = e do
Hi Till,
My guess is that you want to break up a text file into
a list of lines with Parsec. (ie. lines functionality).
A text file consists of non-newline characters seperated by
newline characters:
import Parsec
plines :: Parser [String]
plines = (many (noneOf \n)) `sepBy` newline

Hello Krasimir,
I am very curious about your implementation of the Object I/O system, but
unfortunately could not open the .zip files either (same symptoms as Arjan
van IJzendoorn wrote). Could you check the formats of these files? Thanks
in advance.

After having tried to download the file a few times, I believe
the problem is not in the zip file format, but download failure.

I just just wanted to say that I agree with almost everything Conor said.
I find it a little odd that the extension to Haskell that allows explicit
forall
does not also allow you use explicit type application (and type lanbda).
