Hi, I was playing around after getting the new O'Reilly book with lists
and their operators!
Not sure what the below actually means?
Prelude>  : 
it :: [[a]]
(Got :set +t on )
I thought the first argument of ':' must be an element, so is the empty
list an element of the same type of the contents of the empty list?
Yours confused Paul :-)
