[Caml-list] adding a function to an already existing module

[Francois Berenger <berenger@riken.jp>]

Hello,

Let's say I want to add a function to the List module
of the std lib.

I'd like to do this without having to change list.ml
in the std lib.

And, my function need to have access to everything available
in list.ml (constructors, type names, etc.).

Is this possible and how to do this?

For example, I want to create MyList, and this module
is the exact List module plus some functions of my own.
Then, some of my code would use MyList instead of List.

Thanks a lot,
F.

PS: a full copy-paste of list.ml is considered cheating ;)
