If the original library is well disciplined (i.e. the module table is returned,
and beyond the one inevitable entry, which even in 5.2 "lua -l modname"
gives, there is no pollution of _G), I have usually found it sufficient
to replace one call to luaL_register(L,"modname",funcs) by
lua_newtable(L);
lua_setfuncs(L,funcs,0);
and possibly several calls to luaL_register(L,NULL,subfuncs) by
lua_setfuncs(L,subfuncs,0);
Unfortunately there are some small subtleties, and one may need
to consult
