First of all, the question is about an older version of Iteratee. For

Kevin,
what version of cabal install are you using?
I ask because prior to the 1.10.* version series, cabal would have a much
harder time "correctly" choosing versions of dependencies, which at least
for me often manifested as such confusions in caba regarding selecting
versions. Prior to said cab

It's not OK and it's an artifact of the weak-typing and ill-defined semantics
that pervade iteratee libraries. It's possible to do a lot of bad stuff,
including binding with an iteratee yielding a remainder without consuming input.

Any advice (other than upgrading to 7.0.3, which is not an option at the
moment
It's forbidden for an iteratee to yield extra input that it hasn't consumed;
however, this is unfortunately not enforced by the type system. ___

Which ticket numbers are these? Trac allows one of them to be closed
as a duplicate. Perhaps you can do that, or at least provide those

Maybe the cabal-devel list is also a good one to include on this?
Either way I've added them to the CC list.

Hello cafe.
Haskell wiki told me about continuation-based parser
Data.Binary.IncrementalGet [1] from binary-strict package. I found the
idea very useful and tried to use it. Original library by Lennart
Kolmodin raises some questions. The lib's main data structures are:
data IResult a = IFailed S
I've noticed a lot of packages recently missing documentation links on
Hackage. It looks like the job to build these hasn't been running since
perhaps about Saturday. Are appropriate people aware of this?

I uploaded a package to hackage last Saturday (16th) and the docs are not

Is this a known issue?

Hi,
I found there is similar question as:
http://groups.google.com/group/haskell-cafe/browse_thread/thread/7439262e9ac80dd2/91ca18e11ff00649?lnk=gst&q=QuickCheck+Ord+a#91ca18e11ff00649
I am still think it's very strange. For example:
prop_foo :: (Ord a) => [a] -> Property
prop_foo xs = not (null
