In the process of refactoring some code, I serendipitously created what I think
is an essential new bit of Python syntax. The “or else” statement. I ended up
with:
sites_string = args.sites or else self.config['sites']
which, of course, is a syntax error today, but it got me thinking what we could
do with an “or else” construct. Perhaps an alternative to assertions?
Wouldn’t it be neat to write:
foo == 42 or else
and have that be an synonym for:
assert foo == 42
:-)
