I feel need for both approaches.

So one part of book may illustrate using Lua itself to handle flow:
  * vararg "..." for chaining,
  * tables for wrapping results of C functions and graph representation,
  * metatables for memoizing and creating languages (like LPEG),
  * dynamically loaded fuctions for business logic)

This topics are already described in PiL but I think alternative
descriptions are always good.

And the other part may demonstrate useful libraries for some custom
tasks (luaexpat, dkjson, ltokenp, LPEG, torch, etc). This part probably
may have infinite size.
