self for Jocaml location

[CREGUT Pierre FTRD/DTL/LAN <pierre.cregut@rd.francetelecom.fr>]

I have a weird question :

Is it possible to program a notion of self like you have with Thread.self ()
in Ocaml ? 

The first question is what is self. The answer is the current most internal 
location of my thread. So what I am looking for is :  self : unit -> location

Why do I need it ? In fact the problem is linking a "service" (a
function or a data structure identified by a "name") to the current
location so that i can unambiguously refer to it without naming
where I am. This mechanism has an ambiant flavour.

I am ready to go very deep in the internals of jocaml to get this behaviour : 
is Jprims.self_location the function to look at ?

Then there are two solutions :
 - put the service directly in the location structure :
    Is there a way to extract and call a process definition from the 
    location_stub obtained ?
 - put the service in a global table with a location id as a key
    It is less efficient. A second problem is moving locations. I must
    move the elements using it as a key but also the sublocations.

Thanks for any help !

Pierre
