Re: [Haskell-beginners] safetail problem

_ isn't a value: it's a wildcard character for pattern matching. Also, if x = [1,2,3], [0,x] is the wrong way to make a list. The right way is (0:x) (":" is "cons") What resource are you learning from? On 7/12/11, Roelof Wobben wrote:

Hello,

As a exercise I need to rewrite the tail function into a safetail function by using conditions.

So I made this : http://codepad.org/bKcCUdqy

But as you can see there is a error message.

Can anyone explain me how to solve this ?
