Well perhaps I am biased about my experiences with Python where the file
location and it's name determine the namespace. The Python socket module
for instance has a Python part socket.py and a C part _socket. If you
need to access the C routines then you need to use the _socket prefix.

It took some time to understand that the luasocket C and lua modules
imported into the same namespace and that because I initialized the C part
first caused the lua part not to be loaded. That this needs documentation
and explanation I believe is incorrect when it can be made to just work in
both cases. I am certain that others will/have used time finding out this
and then fixing it in various ways.

This is only really a problem when there is a C module and a lua module
which import into the same namespace. Perhaps in this case a seperate
namespace could be used as a general principle?

Anyway I use your method now to avoid patching your code and as a general
method to solve this problem, thanks for your help.
