I dunno, the new "purer" modules in 5.2 actually seem crazy easy to
use, and also easy to understand if described reasonably:
``A "module" in Lua is just a table containing some functions.
To load a module, you use the "require" function, which takes a name,
finds the corresponding source file, and returns whatever that source
file returns -- which is usually the table containing that module's
functions.
So:
* To _use_ a module, just call the "require" function to find it,
store the table it returns in a variable, and call the functions
in that table as you wish:
local M = require "M"
...
M.oink ();
M.barf ();
...
* To _define_ a module, just make your source file return a table
with your functions. E.g.
local M = {}
...
function M.oink () ... end
function M.barf () ... end
...
return M
''
That seems pretty darn easy to me...
