Unrequiring and unextending make global changes. I think the selector 
namespace ideas being bandied about are a nice way to hook calls within 
a given context without invading core classes or making global changes 
that could break other people's code. In truth, I think good selector 
namespace could actually reduce the need for and danger of 
monkeypatching, since you can make safe localized changes.

If I were to mock up a proposal, which one should I go with first? 
Someone propose me a spec.
