PyON dosn't use exec in order to reconstruct obbject.
It uses python parser for constructing AST and then builds object
using pickle-like protocol from AST.
I guess PyON could be used as standard reconstructable representation
of python objects.

If someone need standard way for reconstructable representation
of almost every python object based on python syntax then PyON is a
possible choice (probably in near future).
Also maybe in the future someone will offer better solution for
reconstructable representation of
python objects based on python syntax.
Also I do not think that PyON should be used instead of JSON.
