static functions are only visible within their own file. Non-static
functions can be called from outside of their own file.

In most Lua modules, the only function you want to export to outside
code is your luaopen_xxx function (which Lua needs to be able to call
to load your module). The other functions are generally only intended
for use by your own module or from within Lua.
