Hi all,
I'll admit, the original idea for this package was something to place in
ACME ;). However, it's goal is to solve a real problem: the lack of good
instances on the Either type. As a brief summary, Either has no Applicative
or Monad instances in the base library, has 2 reasonable definitions

I ran into a segfault while working on some database code. I eventually

This package allows WAI[2] applications to be run on a FastCGI-supporting

Hi Ozgun,
At the moment, I would say that Happstack is your best bet on a mature
option for Haskell web development. There are other systems being developed,
but none have been battle-tested as much as Happstack (as far as I know). I

I know this is basically a rewording of a previous e-mail, but I realized
this is the question I *really* wanted to ask.
We have this language extension UndecidableInstances (not to mention
OverlappingInstances), which seem to divide the Haskell camp into two
factions:

Hi all,
Well, I've got two problems which both want to be solved with undecidable
and overlapping instances. Obviously, I'd like to try and avoid them. For
the record, the problems have to do with the control-monad-failure and
convertible packages. The code below *should* make clear what I'm tryin
