I needed to translate text in my Haskell code and Microsoft Translator[2] seems to be the easiest and cheapest (free 2M chars/month) way to do it. I wrapped my code in this package[1].

I tried to make it easy to use. If you plan to use Microsoft Translator in Haskell but don't want to use my package, I still recommend you look at my source code since the documentation in Microsoft's page appears to be incorrect (I had to see the source code of the Python package to get it to work).
