Is there any reason it couldn't be done in 2.1? What is the planned policy with regards to the visible interface for extensions? It would also be nice to have a rough idea of how the resulting code would be layered, i.e., what is the design for this re-factoring. Simply having a design would be a major step forward. In any case, I think the primary goal for 2.0 should remain the python3k port. Chuck
