Hello,

I think your are confusing 2 things :

- arguments in a function
- arguments in a program

When you do ./test.native [] you give the string « [] » to the ocaml 
program. This is not automagicaly passed to the function  « last ».

Actualy, your program has a function which is never called…

Hope this help,
