[Haskell-cafe] Is there a library that has a strict version of `sum`?

There's a certain tendency for people to look for even trivial canned
solutions, which to my mind misses the point of functional programming.
It's trivial to build exactly what you need from the building blocks you
have, so canned solutions like Prelude "sum" lead both to this kind of
problem when they don't quite fit, and at the same time inappropriately
encourage people to go looking for "more appropriate" canned solutions.
