Hi Laurent,
I registered this account after being a long-time lurker just to weigh in on this topic, so consider this one more vote in favor of camelCase function/method names. Just a personal preference, but it's the way I like it.
However, I would personally prefer if the "get/set/is" naming convention stayed. I really like just being able to type "get" in an IDE, and immediately being able to see all possible things you can... well... get from a class, all neatly in same place (and likewise with "set").
It's all pretty small potatoes, though. As long as the API stays awesome, I can adapt to whatever naming conventions you are most comfortable with.
