inspect.lua
Latest version:
https://github.com/kikito/inspect.lua
inspect.lua will make it easier to debug your tables by generating string representations of them, in a hierarchical way.
It comes with a default "max depth" of 4, in order to avoid "infinite recursion" as well as making its output more intelligible.
Do not attempt to use it for saving/restoring tables from a file. It generates invalid Lua (on purpose). It's a library for debugging and little else.
