Why should someone use a global request if he has a request
available? This package does nothing else then offer a request
if non is available. And if you need a request if non is available
there is something wrong with the application design. Or better
let's say it's another pattern then we use in zope 3 right now.
I fully agree with Christian if he says this is an anti pattern.
Not ure but probably "Reinventing the square wheel" is the anti
pattern was thinking about.
