  I don't use globals in Lua.  Of the actual Lua apps that I have [1] none
use global variables.  I do, however, do put "global" data for the app in
its own table and make it available via require() (usually, require("CONF"))
so I don't have to pass it around everywhere.

  I've also cut down on my use of global variables in C, and when I do have
a global variable, it starts with a 'g', for example, 'g_L' for a global Lua
state.  If it's meant to be read-only, I'll prefix it with 'c', for example,
'c_numaflinks' [2].  For static variables outside of a function, I'll prefix
the variable with 'm' (it makes sense for me).
