This is exactly my point. 

I have this kind of trivial function spread over and over again.
and lots of people have this function as well, maybe a bit different,
slightly imcompatible with each other.

Coding with OCaml would be some much easier if all those trivia would
come directly with the STANDARD distribution. and it would be much more
consistant across 2 differents developers as well.
