It's not really clear to me what you're asking. The function read is a
method of the typeclass Read, and it has type Read a => String -> a.
There are a number of instances of the typeclass Read in the standard
prelude (http://www.haskell.org/onlinereport/standard-prelude.html)
Notably,

Well I think one of the best tools to programme on for Windows is UltraEdit,
it will give you colors and other stuff (provided you get the correct file
for it which is out on the net).
Emacs also exists for windows and is not bad, but I don't know if that is
the best tool (I sure like it but I hat
You may want to have a look there :

It references some tools to develop in haskell ...

You forgot to bind a name to your do-expression. Try:
foo = do x <- a
y <- b
return (x,y)

I'd like to find a reference to reading with patterns such as
read::[(Int,Int)]

Hi, I'm trying to investigate the list monad. I
program
instance Monad [] where
xs >= f = concat ( map f xs )
return x = [x]
a = [1,2,3]
b = "there"
do { x <- a
y <-
b
return (x , y) }
And I get the error
Syntax error in input (unexpected backslash
(lambda))

Hi,
I'm beginning to study Haskell, For the following
a = [1,2,3]
b = "there"
do x <- a
y <- b
return (x , y)
Winhugs cannot run it. Gives
Syntax error in input (unexpected backslash (
lambda))
Your problem is that you're using monads to grab the contents of a and
b, while a and b are

Hi,
I'm working on a version of Simon Thompson's code from "The Craft of Functional
programming" to handle polymorhpic data types.
Heres the question Im working on - Ive tried doing the first part, but i would
really apprecate it if someone could let me know if ive implemented it wrong.
