Newbie question on pairs and ipairs

[Glenn Edgar <glenn-edgar@...>]

Hi

The source code indicates that a lua table consists of two parts, an array 
part and a hash table part.  It also appears that ipairs iterates over the 
array part and pairs iterates over both the array and hash table part.

If my understanding is correct, I would like to ask the following question.

What is the best way to iterate over the keys that are only in that hash table 
part of the table?

Thanks for your help.
