i'm really happy to have learned about something like functional programming and french at the same time. i noticed that there are not enough sources about this style on the net. after first fights with the other paradigm, it's really the better thing. cause i really do like to proof something to be correct than rather try to test it.
another tip is this prof of the university bordeaux 1 who told me about exception-handling in the wonderful c programming language.
