Python, Jython, Pypy, etc - and python standard lexemes

[Borcis]

Suppose you want to hook a CPython process and a JPython process
together, while minimizing "C2J" impedance.

Do we have better than exec statements and eval functions ?

Would it not be in the style of py,
having failed after years to give life
to py's own version of s-expressions,
by way of ast modules and such,
to devise a lexical format,
made to save communicating py processes,
better than 50% over transmitting py source ?

Will there come an age of "meta-lexical" py ?

Should the standard py examples show the unicode
machinery
put to servicing
pure meta-lexical py tasks ?
