[racket-dev] proposal: `data' collection

I do not understand your answer. 

I nominate you for a major speech at PLT day. 
You can get up to 30 mins full time and 30 mins
of discussion time. 

If things aren't clear after that, you will never 
be allowed again to use the words 'coherent' and 

Until then I propose we postpone collects/data/ . 

This is a one-month delay and I think in our interest.
