Why is this ugly? This seems like an elegant solution, to get privileges only
when you actually need them?

Can you motivate why? Any order looks fine to me...

I use whatever my mail client does when I hit "list-reply" :-)

Most email clients have a "followup" or "reply-to-all" feature, that will do
this. Better email clients also support (setting and reading) the

I've found two more little bugs. The first is that version comparison is

Hi Claus,
I've installed the vimball, and it spit a few errors at me. In particular, it
couldn't find the haddock documentation directory. A quick look at
haskell_doc.vim shows that it should autodetect the directory. However, for
some reason my ghc-pkg command returns the doc directory twice:

The download link on this page seems to use \ instead of /, making it not
work.
For anyone eager to download it, just replace \ (or %5C) in your address bar
with \ and it should work.

That's correct.

I use some typing information, but that's mostly hidden away. In

AFAIK this only works when the code has a single author (or, you get a written

Hi all,
I've been reading the gentle introduction to Haskell a bit more closely today
and there a few things which I can't quite understand (presumably because they
are typo's). I've found two issues with the "Using monads" section [1]. Not
sure if this is the right place to report this, but there
Hi all,
for my Master's thesis, I'm looking into functional hardware
descriptions, and in particular to translate haskell code into VHDL that
can be programmed into an FPGA.
For this, I'm using the GHC API to load the haskell source and give me
(simplified) core representation. I then walk over t
