Catching errors thrown with `error`?
either, exception, haskell
Solution
There is no spoon. You didn't hear it from me.
For this particular example, though, you should use `reads` instead.
Problem
There are some stdlib functions that throw errors on invalid input. For example: ``` Prelude> read "1o2" :: Int *** Exception: Prelude.read: no parse ``` I would like to wrap it to return a `Either e a` instead. How can I do that?
