Oh, my pet hate about GNOME is that their idea of "user friendliness" is
drastically slashing
features and functionality that users are crying out for (and ignoring pleas
for re-inclusion). I
swear most of the checkins to GNOME must be on the lines of

I don't think this scales.. if decorators transformations really are as simple
as my regular
expression, then using an intermediate syntax for a decorator and then doing
the appropriate
substitutions would be better. Just as an example, something like:
class Something(controller.Root):
$[[[expose(template="...")]]]
def index(self):
""" ... """
pass
Then when we write the template we can change those to the correct form.
... with a regular expression ;-)
