S-exprs can represent trees of data easily. I am wondering if s-exprs, 
or some other syntax, can be used to represent a graph just on reading, 
without eval.

I assume something simple could be done where you have a syntax to bind 
symbols, and then access their bindings. Does Lisp do this already? or 
is graph data just written as Lisp code and eval'ed?
