Actually, I knew that.
However, given the following expressions are semantically equivalent:

lazy expr;;
lazy_from_fun (fun () -> expr);;

With "lazy_from_fun" being a plain function,
my point is then to know if they are really equivalent
(e.g. implementation wise), so I can assume
the keyword "lazy" is just syntactic sugar.
