Proposal for request global removal

Currently the request context is stored in the request global, which can encourage anti patterns such as accessing the request object from a database model.

I'm thinking that a cleaner approach would be to pass in the request context to the view function itself, rather than having to access it from a global. This object would then be passed around as/where it was needed, encouraging modularity by design.

def some_view(request):
    print request

Could a core maintainer give their thoughts?
