No fair -- that's not a single expression any more!-)

Why do you think it would break?  It would do a _tiny_ amount of
avoidable work, but still return the perfectly correct result.  Sure
you don't think I'd post an unreadable inline hack that would break
in the unlikely case the BDFL ever made a change he's specifically
Pronounced again, right?-)

The BDFL has Pronounced against it: he doesn't LIKE chaining.
