Yes - you are right of course - this was just a minimal example of
course to illustrate the sort of thing I'm using function attriutes
for.

I like this way of doing it, as it is possible I may have a function
that could feasibly be either an assertion or otherwise depending on
context.

The main reason for using a decorator was to avoid problems like the
following whilst providing an easy way of adding the attribute:

>>> def assn_or_other(data):
...     return False
...
>>> # I want x to be treated as normal.
... x = assn_or_other
>>>
>>> # I want y to be an assertion
... y = assn_or_other
>>> y.is_assertion = True
>>> x.is_assertion
True
