[NTG-context] lua tables - how do you cope?

This is less a specific question about ConTeXt than a hope for good advice: I’m maltreating my xml files with a mixture of TeX and Lua. I want to extract and typeset information in different forms, so I first collect everything in lua tables, rearrange and order these tables and typeset the results. All fine and dandy. My problem is that I have to have tables within tables within tables… you get the picture. One aspect of Lua that is really bugging me is the fact that associative tables have no order, which can be a pain in the butt for this kind of operation. So I have to be careful that I have to use constructs that will keep the order in which items have been added and loop through them via ipairs() instead of pairs(). I find it difficult to keep track of what’s inside my layers upon layers of tables. So my question is: how do those of you who are more experienced with this kind of question proceed? Do you have any handy tool to visualize a table? Any tips you want to share?

Thanks a lot!

Thomas
