thank you for the quickly response :)

well... I tried your dir function with a table and it printed the keys
and values for me (not the table's attributes and methods)

and tried it with a userdata and an error has been raised:

(read_query) cached_queries.lua:6: bad argument #1 to 'pairs' (table
expected, got userdata)


thank you also... and maybe your message clarify the clouds are in my
mind :) well... if Lua hasn't objects, means this that most of data
types won't retrieve to me a map of their own attributes and methods?

I mean: in Python, I use dir() to list all that an object has and this
makes me knows that an object has the method that I need, and so on...
this makes me gain hours of research, just using the intuition.

PS: if you are brazilian, let me know if I can send to you in PVT,
maybe using portuguese I can explain better my questions :)

thank you all
