Hello,

I try to solve the 99 haskell problems on several ways.

But my first try which looks like this :

Last2::[a]-> a
Last2:: last[list]

gives the following error message :

src/Main.hs@1:1-1:6
Invalid type signature: Last2 :: [a] -> a Should be of form <variable> 
:: <type>

What am trying to do is say the input is a list which can be of integers 
or chars so everything is the output can then also be of type everything.
