Just the other day I was thinking about something just like this. And
then it could be plugged into something like a XSLT to make
transformations between Lua table graphs. I was considering something
like this to be used in manipulations of parse trees.

Basically redo a given part of the XML ecossystem without XML :-)

(This was triggered with the realization that I was constructing SQL
queries that would just a second later be parsed by a RDBMS -> I
thought it my might be better to communicate my intentions to the
RDBMS with the trees themselves rather than turned them into a
query... but that is off-topic here, I guess :-) )
