There's a bigger issue with trying to make whatever repr() does a codec 
in Py3k. As a Unicode->Unicode transformation, it doesn't mesh well with 
Py3k's strict Unicode->bytes/bytes->Unicode encoding/decoding philosophy.

That said, it would be nice to have a way to easily stack 
Unicode->Unicode transforms on top of text IO streams, or byte->byte 
transforms on top of binary streams.

Cheers,
Nick.
