  Thanks a lot !

So I will not add the use of "|>" to my habits. Simply using "<<" will help to keep things simple.

Only two or three operators seems very useful to me :

This one avoids some parentheses and let the code clear.
let ( @ ) f x = f x

The composition operator :
let ( << ) f g x = f @ g x

This one, written like this, is not a true operator, but is very useful to adapt parameters order :
let flip f x y = f y x

This other one, like "|>", doesn't appear to be essential :
let ( >> ) f g = ( << ) g f
( Can't write : let ( >> ) = flip ( << ) instead... )

Please are they other useful operators ?
