Hi Tanguy,
didn't test it, but how could it be case sensitive? No function is case sensitive in it

I don't know if I did something wrong, but when I tested with a list of integer, it failed to find the numbers more than once. I also tested the example with modification by added an extra name in the second position, the function was broken by returning only "Albert", not "Jean" any more.
