Is it new idea month? :)

That would seem to follow the pattern of combining sequential lines that
end in ':'.

if pay<10 if hours>10 if stressed:
    sys.exit()

That would be the same as using ands.

And this gives us an if-try pattern with a shared else clause.

if trapped try:
    exit = find('door')
except:
    yell_for_help()
else: #works for both if and try! ;-D
    leave()

Which would be the same as:

if trapped:
    try:
       exit = find('door')
    except:
       yell_for_help()
    else:
       leave()
else:
    leave()

Interesting idea, but I think it might make reading other peoples code
more difficult.
