We can also pattern match on the result of a real expression, not just the input. For that, we write:
|
||||
|
||||
\begin{haskellcode}
|
||||
f :: Int -> Bool
|
||||
f x = case x - 2 of
|
||||
2 -> True
|
||||
5 -> True
|
||||
y -> False
|
||||
\end{haskellcode}
|
||||
This allows more powerful pattern matching, especially when we define our own data structures.
