I've been working with Lua 5.0 in a quite complex open source proejct and have found a 
problem that doesn't seem to mentioned before in the list (at least, I did't find 

I have been using Lua tables for a simple object programming - simple in terms of 
implementation but quite complex in terms of contents. My tables usually contain about 
ten variables each, including other tables. Worse, there are methods in every one of 
I would like to create a string representation of this tables, so that I could write a 
representation of them in a file that could be loaded when needed. It is obviously 
possible, but does not seem to right way to me, to write line by line, variable by variable, 
the contents as in a configuration file. Also, writing a string that should be executed by 
Lua (like "table = { a = 5, b = "a" }") could be easier but is a 'dirty trick' (not to mention 
security problems). I have thinking about simple configuration files and methods that 
would act like a constructor for my 'objects', but, before writing this code, I'd like to know 
if someone has a solution for a problem like this.

Thank you,
