Reusing scheme/guile makes a lot of sense.  I think any way that creates 
  a way to have any attribute attached to any piece of data, and then 
sift through your data to produce outputs like netlists, currently 
connected polygons, sets of data like, "the first change going backwards 
in time that doesn't connect this element to that element"  (short 
finder)  etc...

For instance, the short finder would require attaching timestamps of 
some kind to elements.  not a feature you would think of right off the 
bat, but those are easy with a data structure that takes into account 
layout and schematic and simulation needs.
