A String in haskell is just a list of Chars!

How does this look in haskell?

Now let's say we want all numbers between 50 and 100 that have the remainder 0 when divided by 12:
\pause
\begin{haskellcode}
\begin{haskellcode*}{bgcolor=mygrey,frame=single,numbers=none,label=GHCi}
> [x | x <- [50..100], mod x 12 == 0]
\end{haskellcode}
\end{haskellcode*}
\code{x <- [50..100]} is the binding, while \code{mod x 12 == 0} is the predicate, separated by a comma. We can have multiple predicates.
