Indeed the doc for 2.0 is really comprehensive, but didn't the library
evolve a lot between release 2.0 and 3.1 ?

It is a fun and largely flawed competition between languages and their

What's an elegant definition of a Haskell function that takes two strings
and returns Nothing in case the first string isn't a substring of the
first, or Just i, where i is the index number of the position within the
first string where the second string begins?
my quick take, with Maybe and

This should be mapM_ and 'ghc -Wall' spots this problem since 6.12.

Indeed, that's not part of -Wall.

Hem hem ... I should never try to write anything sensible before putting

Although it's a bit off topic, I must say I agree with Malcolm on that.
