Dear list,
with rewrite rules I can tell the compiler to replace map id by id,
but I still have to write that rule by hand.
Does anyone of you know about research into inferring such a rewrite
rule automatically? I could imagine that for a function of type f ::

The only paper that comes to my mind is Wadler's Theorems for free. It's an
old one and not
exactly about rewrite rules, but it may be a good starting point.

Again we will teach an Applied Functional Programming Summer in Haskell
school this year at Utrecht University. In the previous four occasions students
were all very happy with the school and we plan to repeat this success this
year.
Among the intended audience are prospective master students

It seems to me that the second variant would work as well:

Work on deforestation might also be relevant.

Would it be possible for you to create a 0.4.6.1 with this bugfix

Hello haskellers,
I'm presenting the third version of JuicyPixels. As the version number
indicate, this is a major version with backward compatibility break. The
major reason behind this breakage is the introduction of High Dynamic Range
images. High Dynamic Range images are used in photography,
Hi everybody,
What is the state of container libraries? I am looking for a library which
provides:
* unordered containers (for operational type safety, I don't want to
impose orders on things that don't have them -- unordered containers does
this)
* can handled nested containers (containers

I created the following page on the wiki to capture one pattern that
occurs often in Edward Kmett's lens library.

Feel free to rename it or add comments, examples, clarifications,
additional notes or extensions to the technique.
Sorry to be reviving this thread so long after but I seem to be running
into similar issues as Michael S. did at the start.
In short, I'm using forkProcess with the threaded RTS, and see occasional
hangs:
- I see these only on Linux. On Mac OS X, I never do.
- I'm using GHC 7.4.2

The program looks like this:

factorial n = product [1..n]

And that yields 0 (no errors). Is it a bug or feature? :)

Hello cafe,
Just FYI:
I wrote an tutorial, Up-front Unit Testing in Haskell. It is about
how to use doctest, hspec and Cabal.
Enjoy!

Quite informative, thank you. It was nice to see how to combine the
suites together as most places only show how to use one.
The mention about Travis CI is also much appreciated; it seems like a
really good project and I will definitely be using it in the future.

I just looked at this code and since I don't know the code I can't give you
good solutions, but for others watching this thread the links might prove
interesting.
My main theory is that you do have some other thread in FFI-land while you
are fork()ing. The task-cond, task-lock seems to be
