V? and generics

[Brian Goetz]

The question about "what about F-bounds" is a good one; thanks for 
raising this.  Needs further thought.

But, while I agree you've raised a problem, I think it's a pretty big 
leap to the "solution" you propose.  So let's table that (re-)proposal 
pending a deeper understanding of the problem, and its relation to the 
other requirements.
