Hi,

Indeed, the following operator definition is pretty common on OCaml code in the wild:

let (!!) = Lazy.force

However, I'm not sure it should be part of a standard library.  There are projects which
do not use Lazy, and instead define the (!!) operator to be something else convenient
for whatever task they perform.

Best regards,
Dario Teixeira
