Hmm. I'm not so sure about that. Side effects are fine in a list comp,
as long as you're making use of the return values. For instance, if
you have a function that inserts a record to a database and returns
the new ID, you could reasonably use a list comp to save a bunch of
records and get a list of IDs for subsequent use.
