DIP 1017--Add Bottom Type--Formal Assessment

[Mike Parker]

Given the nature of the feedback in both review rounds this DIP 
has gone through, Walter has decided to reject his own DIP. He 
still believes there is a benefit to adding a bottom type to the 
language, but this proposal is not the way to go about it. He 
hopes to revisit the issue in the future.

Thanks to everyone who provided feedback.
