I played around with this some more. You can see some files at
http://www.dtek.chalmers.se/~d95mback/gettext/ if you are interested.

The use of unsafePerformIO may be unsafe here, I really haven't got a
clue.

When in doubt, use i18n instead of __ :)

Output examples:

martin@lexie:~/gettext$ LANG=sv_SE ./Main
Hej världen!
1 Jedi trained I have.
martin@lexie:~/gettext$ LANG=en_US ./Main
Hello, world!
I have trained 1 Jedi.
