Oh, yah, trust me... I think it is awful, too. In my own code, I wouldn't
use either trick. i'd just write:

  if ex.code:
    print 'FAIL',
    print 'PASS',

I was just having a bit of fun. But seriously, that and/or "trick" is a
somewhat standard idiom for a Python ternary operator. Frickin' ugly, but
there ya go.

[ altho it is limited as a ternary operator. if you have:
    X and Y or Z
  and Y is a "false" value, then the result is Z. Brane's form will always
  return Y, whether it represents a true or a false value. In this concrete
  case, Y was a "true" constant value, so it was safe. ]

hehe... I *did* say it was for Python Fu Masters. That is another way of
saying it was for people who prefer Perl's opaqueness. :-)
