It's not working because you don't have a definition for take'. If you
want to fill it in later you can just do:
take' = undefined

Because GHC is limited
in GHC you cant do
double a = a * a
you have to put into let like this
let double a = a * a
Cheers!

Very attractive book. I'm really enjoying this book.
Anyway I have one question,
Why I can't declare func type like books?
I got always error about 'lacks an accompanying binding', like this,
Prelude> :l baby.hs [1 of 1] Compiling Main ( baby.hs, interpreted )
baby.hs:32:1: The type signature for take' lacks an accompanying binding Failed, modules loaded: none.
Here is codepad link, http://codepad.org/ttZRBpkL
Thanks.
