I used ALUT on OSX and it worked perfectly. Not used it on windows yet,
but according to the documentation it's supported.
Have a look here for how to use it on windows:
https://hackage.haskell.org/package/OpenAL
and here for some examples:
https://github.com/haskell-openal/ALUT/tree/master/examples/Basic
Best,
Tilmann

Hi all,
I understand that the take method will evaluate the value inside the cons
cell whereas length will just evaluate the spine or structure of the list
λ> let y = "abc"
Prelude|
y :: [Char]
λ> :sprint y
y = _
λ> take 1 y
"a"
it :: [Char]
λ> :sprint y
y = 'a' : _
λ>
Well and good but why doesn't the same work on a list of Nums??
λ> let x = [1,2,3]
Prelude|
x :: Num t => [t]
λ> :sprint x
x = _
λ> take 1 x
[1]
it :: Num a => [a]
λ> :sprint x
x = _
λ>
I expected to see x = 1 : _

Best Regards,
Boon Hui

Maybe this will help answer some questions and raise others:
. let x = [1,2,3]
. take 1 x
[1]
. :sprint x
x = _
. let x = [1,2,3] :: [Int]
. take 1 x
[1]
. :sprint x
x = [1,2,3]
