The above is nice and simple, but it only solves a subset of the
problem that auto_escaping is designed to solve. The missing
component is filters: for filters to be truly chainable, they need an
awareness of if their input is escaped or not. The 'unorderedlist' vs
'escaped_unorderedlist' discussion from a while back is a good
example of that. This is covered in more detail in the proposal on
the wiki.
