[Haskell-cafe] ANN: loop - fast for loops

[Niklas Hambüchen]

Announcing the first version of the loop package:

http://hackage.haskell.org/package/loop

This is for iterating over numeric or otherwise iteratable things in a
fast fashion. Looks like C, runs like C.

It's trivial, but very robust performance-wise and more independent of
GHC smartness or non-smartness in regards to optimising alternatives
like `forM_ [1..n]`.

It comes with a lot of benchmarks.

Contributions are very welcome.
