Hi,
Can someone please give me a _lucid_ and _simple_ explanation of exactly how
continuations can be used in Haskell?
I've already had a look at most of the tutorials and explanations on the web,

Hi Heinrich,
I'm really looking to use the Cont monad itself--but the link you gave me is
also helpful, so thank you.
If anyone else has words of wisdom to add to this thread please feel free to
pitch in.
Thanks,
Mark

Having worked with the operational-package, I only can recommend it. In fact
I was trying to do the same thing you are now.
The only thing is that operational needs the use of GADTs, which come as an
extension, but still are a useful and heavily used feature.

Thanks to Simon Marlow for helping me resolve this problem. After step 2,
delete the following directories from the source tree:
libraries/dph
libraries/vector
libraries/primitive
then proceed with step 3 and 4 (boot, configure, make). This worked for me.

Hello.
When studing programming languages I have learned that parameter is a
variable (name) that appears in a function definition and denotes the
value to which the function is applied when the function is called.
Argument is the value to which the function is applied.
The parameter allows the
I think every people will have different terms.
For instance, for my teachers, argument and parameter were synonyms, and :
in the definition :
f x = x + 3
x was a _formal_ parameter (or argument)
and in
f 32
32 was the _effective_ parameter.
So, short answer: don't bother.

You'll need to capture the functions as serializable data while it
Hello,
I think you have to remember that is x in

If you look at
g (_:xs) = xs
(_:xs) is something similar as a name. You might say '(_:xs)' stands for the
parameter (you can't say it is the name of the

I have released 'Peggy' a new parser generator .
It is based on Parsing Expression Grammer (PEG) [1],
and generates efficient packrat parsers.
How does it compare to frisby?
