Yes, but then pychecker complains about a statement with no apparent effect,
hence the extra verbiage.

My question wasn't about a less ugly way to type what I type now.  It was
about whether injecting "set" into the builtins (so I can dispense with the
above cruft altogether) is likely to cause problems.  I think not, certainly
based on what little surveying I've done at work.  I was hoping someone else
had already tried this and could report on their experience.
