Is that certain? I haven't been following the process discussions, so 
I'm just asking the question. For example, given that you are already 
looking at PEP 580, would it be possible for you to handle PEP 580 as 
official BDFL-Delegate (even if there is no BDFL)?

First of all, it's too early for a proof-of-concept of native C calling. 
We first have to design the theory before we can start implementing 

But even if we could start to write a proof of concept, I would really 
prefer doing that on top of PEP 580. There are two reasons for this:

1. If PEP 580 is rejected, I very much doubt that the native C calling 
protocol will be accepted.

2. I would be good to use PEP 580 as a framework for the implementation. 
Otherwise we have to implement it twice: once before PEP 580 with the 
proof-of-concept and then again after PEP 580 with the "real"
