Now pyon can represent recursive lists and dicts:

>>> lst = ['foo']
>>> lst.append(lst)
>>> pyon.dumps(lst, fast=False) # fast mode is similar to pickle's fast mode
_p__0=['foo',None]
_p__0[1]=_p__0
_p__0

>>> d = {'a':'foo'}
>>> d['b'] = d
>>> pyon.dumps(d, fast=False)
_p__0={'a':'foo'}
_p__0['b']=_p__0
_p__0

I will commit changes to sources this evening.
