I set up my views using classes (the actual views are methods) that
extend a base class. In the base class I set up globally accessed
variables to self so that all classes extending that base class have
access to them - it's more or less for convenience.
I also use the Pylon-esque context object pattern to make a globally
accessible "c.attrib" object available in my templates.
I also use this, mostly for the session's user object which I cache into
redis.
