Another place where this would be very usefull is the following :
Actually there are two installation schemes for ocaml packages :
* Some install their stuff in a subdirectory of /usr/.../lib/ocaml. and you
have to tell the system that you are using this directory. One example of
this is the ocamltk package i think.
* Others simply put their stuff in /usr/.../lib/ocaml. This is a problem,
because it can produce name clashes, but modules put there are directly
accesible without further work.
One advantage of the first approach was that you can then easily remove all
stuff from said package by removing the subdirectory. This was a concenr in
the past, but nowadays, with propper packaging support this is no more a
Also there is still a name clash in the first way of doing things, if there is
the same module in the ocamllib directory, and in the package.
With directory as modules support we use the cleaner first aproach, as well as
avoiding any name clashes.
This will become more and more a concern as ocaml support grows larger.
Any chance to see something like this in a next release ?
Anyone willing to write a patch to test this (now that ocaml if free software)
