Hello Haskellers!
I'm going to give a talk on Haskell at Ubucon 2012 in Berlin (In
German). I want to give an introduction about the concept of functional
programming and the special language concepts of Haskell.
Any ideas what to focus on?
Yours, Robert Clausecker

mentioned.
Maybe Monad is not the best name for that class if it's not true that
every Monad is a
Functor, but it's not very confusing anyway.
Cheers,
Ivan

That does not play well with type inference.
I understand that. But it may be
in advance for all answers, yours

an appropriate term for
concepts of Haskell, like types (Typen) or type classes (Typklassen).
But I really don't know how to call kinds and sorts in German. Any
ideas?

Hi all!
I want to write my Facharbeit (kind of an essay you have to write on a
specific topic you can choose yourself for highschool graduation) about
the type-system of Haskell
file by hand.
Yours, Robert Clausecker

Hello!
I found out, that GHC implements typeclasses as an extra argument, a
record that stores all functions of the typeclass. So I was wondering,
is there a way (apart from using newtype) to pass a custom record as the
typeclass record, to modify the behavior of the typeclass? I thought
about
. Is it possible, and
if yes, how is it possible, to compile a projectwritten in
Haskell using CMake?

Thank you all for the responses. Here's an example:
As I alrerady said, I tried to parse the MMIXAL assembly language.
Each instruction has up to three operands, looking like this:
@+4 (Jump for bytes forward)
foo (the string foo
'0'(1+2)
etc. A string literal may contain anything
of
strings and tries other parsers afterwards, which leads to strange
results. Is there a way to force the whole parser to fail, even if
there's an alternative parser afterwards?
I hope, you understand my question.
Yours, Robert Clausecker

, even if I can implement
it in one line, is there any reason why it's not in the libs?

It probably is, but definitly not portable. Try to find /dev/urandom
under Windows.

would be to use CPP, but is there any flag for
the wordsize?

, the input comes from a lazy list and is than folded into
the Map by insertWith (+) j 1 r. Is there any nice, quick way to do this
with Arrays without using mutable ones?

install additional libs there?
How can I install GHC 7 parallel to GHC 6.12 with the option to choose?
My OS is GNU/Linux, my Distro is Ubuntu (Lucid).
Thank you very much, yours Robert Clausecker
