    Hello Julien,

    no warning should be issued in this case since you have polymorphic 
function:
applying g to () you will definitely have f x of type unit :)
    Try another one:

    let f x = x+1
    let g x = f x; 1

    Now you'll get the warning since the compiler can ensure that type 
of  f x can never
be unit.

    Best regards,
    Dmitry.
